Answer 1

The volume of a cone is: \[\frac{ 1 }{ 3 }\pi r ^{2}h\]

Answer 2

ok

Answer 3

So let's input them into the equation.

Answer 4

The radius in this figure is 15, right?

Answer 5

in think brb

Answer 6

Answer 12

So what is 15 x 15?

Answer 13

@jabez177 225

Answer 14

divide by 7 right

Answer 15

Nope.
You have to now multiply the height which in this case the height is 9 so 225 x 9 = ?
