Question

HELP PLEASE Three cylinders have a height of 8 cm.... Find the volume of each cylinder. Round all answers to the nearest hundredth. Use 3.14 for pi.

Answer 1

Explanation:

The volume of the cylinder is calculated by multiplying the area of its base by its height. The height of the cylinder is 8 inches (the height of the cube through which it is being drilled). Therefore, its volume is πr2h = π * 3.752 * 12 = 168.75π in3.

Answer 2

Explanation:

Just use the equation for volume of a cylinder

For cylinder 1

V=(3.14)r^2h

V=(3.14)1^2(8)

V=(3.14)(1)(8)

V=25.12 cm

For cylinder 2

V=(3.14)r^2(h)

V=(3.14)(2^2)(8)

V=(3.14)(4)(8)

V=100.48 cm

For cylinder 3

V=(3.14)r^2(h)

V=(3.14)(3^2)(8)

V=(3.14)(9)(8)

V=226.08cm

If your confused or have a question just ask

Hope this helped :)
