Volume of a cylinder = pi x (radius squared) x height

Volume of a cylinder with a diameter of 10 inches (and therefore a radius of 10/2 = 5 inches) and a height of 20 inches is:

pi x (5 squared) x 20 cubic inches

= 3.14 x 25 x 20 cubic inches

= 1,570 cubic inches.

Volume of a cylinder with a diameter of 10 inches (and therefore a radius of 10/2 = 5 inches) and a height of 20 inches is:

pi x (5 squared) x 20 cubic inches

= 3.14 x 25 x 20 cubic inches

= 1,570 cubic inches.

Developing

r = diameter / 2

r = 5

V = pi * r² * h

V = 3.14 * 25 * 20

V = 1,570

r = diameter / 2

r = 5

V = pi * r² * h

V = 3.14 * 25 * 20

V = 1,570

Area of a circle = pi x (square of the radius).

Radius of the Frisbee = diameter / 2 = 12/2 = 6 inches.

Area of the Frisbee = pi x (6 squared)

= 3.14 x 36

= 113.04 square inches.

Radius of the Frisbee = diameter / 2 = 12/2 = 6 inches.

Area of the Frisbee = pi x (6 squared)

= 3.14 x 36

= 113.04 square inches.

Two angles are supplementary. The first angle measures 60°. The measurement of the second angle is 120°.

180° - 60° = 120°

180° - 60° = 120°
