You have a job filling cylinder-shaped tubes with flavored sugar. Your boss asks you to find the volume of a tube that is 21 inches long. The radius of the tube is 0.5 inch. What is the volume of the tube? Use 3.14 to approximate pi. Round your answer to the nearest hundredth. A) 5.25 B) 32.97 C) 16.49 D) 65.94

Respuesta :

To find the approximately volume you will use the formula for finding the volume of a cylinder:

V = pi x r^2 x h
      3.14 x 0.5^2 x 21
V = 16.485

The volume is approximately 16.49 cubic inches.
The answer is 16.49.

The volume of a cylinder is given by
V=πr²h.

For this volume, we have:
V=3.14(0.5²)(21) = 16.485 ≈ 16.49
