Question

PLEASE HELPP!

A cylinder has the volume of 1000 pi show with working that if the height = 20cm then the radius = 5 cm.

Answer 1

5^2 = 100

100 x 3.14 = 314

Now we multiply by 20 since it's the height.

314 x 20 = 6,280 cm^3 is your answer.

Formula of cylinder:

H x πr^2

Height x pi(3.14 or 22/7 depending what they tell you to use for pi) x radius being squared (your radius is half of your diameter or given radius).
