$\Large V_{cone} = \dfrac{1}{3}\pi r^2 h$

mathstudent55 · Answer

Use the formula above to find the volume.

sstradic · Answer

can u explain the formula pls

mathstudent55 · Answer

$\pi$ is 3.14 as your problem tells you.

r is the radius of the cone. You have a diameter of 4 in., 
so your radius is half of that, or 2 in.

h is the height of the cone which is 9 in.

Use the numbers above in the formula and evaluate the expression.
