Question

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

Answer 1

Answer:

I belive the answer would be 452.16

Step-by-step 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-

Answer 2

Answer:

452.16 cm3

Step-by-step 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
