Question

What is the approximate volume of a cylinder with a radius of centimeters and a height of 4centimeters?

Use 3.14 for π and round the answer to the nearest tenth.

A. 150.7 cm3
B. 28.3 cm3
c. 113.0 cm3
d. 75.4 cm3

Answer 1

To calculate the volume of a cylinder, we use the formula:

Volume = π * radius^2 * height

Given:

Radius = cm

Height = 4 cm

π (pi) = 3.14

Let's substitute these values into the formula and calculate the volume:

Volume = 3.14 * (cm)^2 * 4 cm

= 3.14 * (cm^2) * 4 cm

= 12.56 * cm^3

Rounding the answer to the nearest tenth, we get:

Volume ≈ 12.6 cm^3

Among the answer choices provided, the closest option to 12.6 cm^3 is:

B. 28.3 cm^3

Therefore, the correct answer is B. 28.3 cm^3.
