Question

Can someone please explain how to do this? thank you!

Answer 1

452.16 cm3

Explanation:

Volume = BH Area of Base times Height

Area of Circle = PiR^2

4x4x3.14 = 50.24

So, Area of Base = 50.24

Area of Base times Height (9)

50.24 x 9 = 452.16 cm3

Answer 2

I belive the answer would be 452.16

Explanation:

The formula to find the volume of a cylinder is
`v=\pi r^2h`

h = height

r = radius

The radius for this is 4 and the height is 9

instert your number into your equation
`v=\pi (4)^2(9)`

and from there i would just put it into a calculator and you get
`144\pi` or 452.3893-
