Areas and Volumes

Figure Areas Volume
Sphere 4 * Pi * R2 (4/3)PiR3
Cylinder With Circular Base Base Area = R * R * Pi

Lateral Area = 2 * Pi * R * H

Total Area = 2PiRH + 2PiR2     

PiR2H
Cylinder With Elliptic Base Base Area = R * r * Pi

Lateral Area = (R + r) * Pi * H

Total Area = (Base Area) + (Lateral Area)

R * r * Pi * H
Right Cone                          /------
Slant Height S = VR2 + H2

Lateral Area = PiRS

Total Area = PiR2 + PiRS
