Question

The volume formula for a cylinder is V = π r ²h.

 Using the symbol π in your answer, find the volume of a cylinder with a radius, r, of 3 cm and a height of 17 cm

Answer 1

Hello, thank you for taking the time to post your question!

The underlying formula we want to use here is V = pi*r^2*h

For this question, we’re plugging in r = 3 and h = 17 to get

V = pi * (3)^2 * 17

= pi * 9 * 17

= 153pi

meaning that the volume of the cylinder for this scenario is 153pi cm^3

I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)

Answer 2

V= pi(3)^2(17)

= 9x17pi

= 153pi cubic centimeters
