4. a cone has a height of 4 and a base area of 9pi. what is it's volume?

show work

V= 1/3 times pi times radius squared times height

V= 1/3 • 3.14 • 4.5 squared • 4(4.5 because 9 divided by 2)

V= 1/3 • 3.14 • 20.25 • 4

V= 1.0466 • 81

V= 84.7746 units cubed

If told to round to nearest tenth then 84.8 , if hundreds then 84.78
