Three cylinders have a height of 8 cm. Cylinder 1 has a radius of 1 cm. Cylinder 2 has a radius of 2 cm. Cylinder 3 has a radius of 3 cm. Find the volume of each cylinder.

Respuesta :

Answer:

Step-by-step explanation:

The volume formula for a cylinder is B*h

B : the area of the base

h : the height

Cylinder 1

The volume is 8pi

Cylinder 2

The volume is 32pi

Cylinder 3

The volume is 72pi

Answer:

Cylinder 1:  V = 8π

Cylinder 2:  V = 32π

Cylinder 3:  V = 72π

Step-by-step explanation:

The volume of the cylinder of radius r and height h is calculated using the form:  V = π r² h

Cylinder 1:  r = 1 cm  and  h = 8 cm

Volume of Cylinder 1 = π r² h = π 1² * 8 = 8π

Cylinder 2:  r = 2 cm  and  h = 8 cm

Volume of Cylinder 2 = π r² h = π 2² * 8 =  π * 4 * 8 = 32π

Cylinder 3:  r = 3 cm  and  h = 8 cm

Volume of Cylinder 1 = π r² h = π 3² * 8 = π * 9 * 8 = 72π
