Question

How many cubic centimeters of water will approximately be required to fill a cylinder with a 3 cm radius and 7 cm height?

A. 63
B. 66
C. 132
D. 198
E. 496

Answer 1

V = π(3²)(7) = 63π cm³ = about 198 cm³

The correct answer is D.

Answer 2

Approximately 198 cubic centimeters of water will be required to fill the cylinder.

Step-by-step explanation:

To find the volume of the cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, the radius is 3 cm and the height is 7 cm.

Substituting these values into the formula, we get V = 3.142 × (3 cm)² × 7 cm ≈ 198 cm³.

Therefore, approximately 198 cubic centimeters of water will be required to fill the cylinder.
