The volume of a cylinder can be expressed as V=πr2h, where r is the radius, and h is the height of the cylinder. Use the tools provided to complete the formula for the volume of a cylinder when solved for the radius, r.
r=?
Answer:
r = [tex]\sqrt{\frac{V}{h\pi } }[/tex]
Step-by-step explanation:
V = πr²h ( isolate r² by dividing both sides by hπ )
[tex]\frac{V}{h\pi }[/tex] = r² ( take square root of both sides )
[tex]\sqrt{\frac{V}{h\pi } }[/tex] = r

A lorry is travelling at 13.5 m/s along a stretch of road where the speed limit is 50 km/h. 1 kilometre = 1000 metres 1 hour = 3600 seconds Show that the lorry is travelling below the speed limit.
The lorry is travelling below the speed limit.
What is Unit of measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that A lorry is travelling at 13.5 m/s along a stretch of road where the speed limit is 50 km/h
We know that 1 kilometre = 1000 metres
1 hour = 3600 seconds
It will do a lot more than that in an hour
13.5×3600 m/h
13.5×3600 / 1000 km/hour
= 48.6km/hour
That is definitely less than 50km/h

The solution to the two equations will be (0,2).
What is a system of equations?A finite set of equations for which we searched for common solutions is referred to in mathematics as a system of equations, also known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.
Given that there are two equations:-
g(x) = 3x + 2
f(x) = | x - 1 | + 1
The solution of the equations can be calculated as:-
- ( x - 1 ) + 1 = 3x + 2
-x + 1 + 1 = 3x + 2
4x = 2 - 2
x = 0
The value of the dependent variable is:-
y = 3x + 2
y = 0 + 2
y = 2

a company has given you the task to research the amount of snowfall in cleveland from december to february. would you be more interested in looking at the mean, median, or mode?
The number of measurements, and the mode being the most frequently occurring value among the snowfall measurements.
The mean, median, and mode are all useful measures of central tendency when researching the amount of snowfall in Cleveland from December to February. The mean is calculated by adding up all of the snowfall measurements and dividing that by the number of measurements. For example, if there were 4 snowfall measurements of 10, 20, 30 and 40 inches, the mean would be 25 inches (10+20+30+40 / 4). The median is the middle value of the snowfall measurements when they are arranged from least to greatest. In this example, the median would be 25 inches as well. The mode is the most frequently occurring value among the snowfall measurements. In this example, the mode is also 25 inches.

to what decimal place should each answer be rounded? how many significant figures does the rounded answer have?
The number of decimal places should be one more than the least accurate measurement, and the number of significant figures can be determined by counting the digits in the number, excluding the decimal point.
Rounding a number is important when providing an answer to a calculation or question. The number of decimal places and significant figures the answer should be rounded to depends on the accuracy of the answer that is required.
To calculate the number of decimal places and significant figures the answer should be rounded to, the general rule is to round to one more decimal place than the least accurate measurement. For example, if the least accurate measurement used in the calculation is rounded to two decimal places, the answer should be rounded to three decimal places.
The significant figures of the rounded answer can be determined by counting the number of digits in the number, excluding the decimal point. For example, the number 6,782 would have four significant figures, as there are four digits in the number.
In conclusion, the number of decimal places and significant figures the answer should be rounded to depends on the accuracy of the answer that is required.

on the sldt, why is a standard score of 89 considered below average if the mean is 100 with a standard deviation of 15?
A standard score of 89 is considered below average because it is 11 points lower than the mean, which is a deviation of more than 0.7 standard deviations below the mean.
A standard score of 89 is considered below average because it falls below the mean score of 100. This is because it is 11 points lower than the mean, which is a deviation of more than 0.7 standard deviations below the mean. The standard deviation is a measure of the spread of the data, where higher values indicate more spread out data. In this case, the mean score of 100 has a standard deviation of 15, which means that any score lower than 85 (100 - 15) is considered below average. A score of 89 is 11 points below the mean, which is a deviation of more than 0.7 standard deviations. This indicates that it is lower than the average score, and therefore considered below average.

The area of the smaller trapezoid is 39 ft².
What is Similarity?Two figures are said to be similar if they share the same shape. Congruent objects are those that are precisely the same size and shape.
Given:
The area of the larger trapezoid is 61 ft².
and, side of smaller trapezium, a = 24 feet
side of larger trapezium, b = 30 feet
So, Area of the larger trapezoid / Area of the smaller trapezoid = b² /a²

a bag contains 9 blue marbles and 1 green marble. what is the probability of drawing a blue marble (no replacement) followed by a green marble?
The probability of drawing a blue marble (no replacement) followed by a green marble is 2/207
Total marbles: 2 + 9 + 18 + 10 + 7 = 46
In the first scenario, the likelihood of getting a red marble is 2/46=1/23.
Since there are now 45 marbles, the probability of drawing a purple marble in the second scenario is 10/45, or 2/9.
Therefore, the likelihood of taking out a red marble in the first scenario, failing to replace it, and taking out a purple marble in the second scenario is 1/23 * 2/9.
