• • • Computing the Volumes of Cylinders
V = πr
x h
2
This is the formula for computing the volume of a cylinder:
r = 3 cm
• Multiply the radius times itself.
• Multiply that product times 3.14.
h = 4 cm
• Multiply that product times the height.
• Express the answer in cubic units.
V = πr
x h
2
V = 3.14 x 3 cm x 3 cm x 4 cm
r = 3 cm
V = 113.04 cm
