A cone and a cylinder have equal bases and equal altitudes T

A cone and a cylinder have equal bases and equal altitudes. The volume of the cone is what fractional part of the volume of the cylinder?

Solution

The volume of a cylinder = (pi)r^2(h)
#1: square the radius
#2: multiply the result by pi = 3.14
#3: multiply the answer by the height
The volume of a cone = 1/3 (pi)r^2(h)
#1: square the radius
#2: multiply the result by pi = 3.14
#3: multiply the answer by the height
#4: muliply the answer by 1/3
The volume of a cone is 1/3 the volume of a cylinder.
