Answer 2

No..

Answer 3

okay well google volume of a cone formula and find out :)

Answer 4

The volume of a cone is 1/3(Area of Base)(height) = 1/3 π r2 h

Answer 5

okay great so know plug in all the information you know into \[v = 1/3 \pi r^2 h\]

Answer 6

hint v = 565.2 and h = 15

Answer 7

now show me what you get

Answer 8

Replace each variable with the shown value.
Then solve for r^2.
