Question

A cylinder has radius 9 inches and height 15 inches.
Find the volume of the cylinder.

A cone has the same radius and height.
Find the volume of the cone

What fraction of the cylinder’s volume is the cone’s volume?

Answer 1

Answer:

Step-by-step explanation:

volume of cylinder = $\pi$r²h

= $\pi$*9*9*15

= $\pi$1215 inches

volume of cone = 1/3$\pi$²h

= 1/3 * 1215$\pi$

= 405$\pi$ inches

volume of cylinder = x volume of cone

= $\pi$r²h = 1/3 $\pi$r²h

∴ 3 times the volume of cone is equal to the volume of the cylinder
