A cone has a diameter of 3 inches. The cone holds 12 cubic inches of water. To the nearest inch what is the height of the cone?
The formula for the volume of a cone is (1/3) • pi • (radius of base)2 • height = V
Substitute the numbers you have (1/3) • 3.14 • (1.5)2 • h = 12
Do the preliminary arithmetic (1/3) • 3.14 • 2.25 • h = 12
2.36 • h = 12
Divide both sides by 2.36 h = 5.09
Round to nearest whole inch height = 5 inches
