Question

A cylindrical cup is 10 centimeters in height. When filled to the very top, it holds 500 cubic centimeters of water. What is the radius of the cup, rounded to the nearest cm? (The volume of a cylinder is V=\pi r^2hV=πr 2 h where r is the radius, h is the height, and V is the volume)

Answer 1

4

Explanation:

the formula for radius is

`r=\sqrt{(v)/(\pi h ) }`

so. 500 divided by pi times 10. then square root your final answer. cool. let's get started.

3.14*10 is 31.4, you can do that without thinking.

500/31.4=15.92

`\sqrt{}`15.92= 3.99, or just 4

the radius is four.
