Volume of cones

The volume of a cone is given by:

Volume = Area of base x Height
V=r2H

where r is the radius of the circle and H is the height of the cone.

The formula for the volume of a cone can be determined from the volume formula for a cylinder because it takes the volume of three cones to equal one cylinder.

Find the volume of the cone:

V=r2H

V=52·10 = ·3.142x52x10

V = 261.83 cm3


What is the volume of this cone when r=3, and h=27?


Use =3.14
