Find the volume of a cylinder with a diameter of 10 inches and a height of 20 inches.
A. 6,280 cu. in.
B. 1,570 cu. in.
C. 62.8 cu. in.
D. 705 cu. in.

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 = 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.

The volume of a cylinder with a diameter of 10 inches and a height of 20 inches is: "1,570 cu. in".

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.

The diameter of a Frisbee is 12 inches. and the area of the Frisbee is: "113.04 sq. in".

Developing

Diameter = Radius * 2

r = 12 / 2 = 6

Area = pi * r^2

Area = 3.14 * 36

Area = 113.04

Developing

Diameter = Radius * 2

r = 12 / 2 = 6

Area = pi * r^2

Area = 3.14 * 36

Area = 113.04

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

180° - 60° = 120°

180° - 60° = 120°
