Order the Cylinders from least volume to greatest volume.
ICE Princess25 [194]

Answer:

Step-by-step explanation:

Hello there, to answer this question, one must know the formula of area of a circle.

1. Use formula for area of circle to find area of base of cylinder

2. Multiple area of base with height of cylinder for volumne

Area = pi * r * r

Cylinder A:

Area: pi * 6 * 6 = 113.1 inches square

Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube

Cylinder B:

Area: pi * 5 * 5 = 78.54 inches square

Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube

Cylinder C:

Area: pi * 4 * 4 = 50.27 inches square

Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube
