Question

April is filling six identical cones for her piñata. Each cone has a radius of 1.5 inches and height of 9 inches.

What is the total volume of the cones?

Answer 1

Formula for the volume of a cone = 1/3h(pi)r^2

1.5(which is r or the radius) squared is equal to 2.25.

Multiply by the height (9) and you get 20.25.

Multiply by 1/3, and get 6.75.


Finally, multiply 6.75 with pi.


6.75pi is equal to the volume of one cone.

Then, multiply by 6.
