Question

The cylinder shown has a lateral surface area of about 80 square inches. Which answer is closest to the height of the cylinder? Use 3.14 to approximate pi.

Answer 1

$\huge\sf{Answer:-}$

We have the following data:-

• Al (lateral surface area) = 80 in²

• R (ratio) = 4 in

• h (height) = ? (in inches)

Adopt : π ≈ 3.14

We apply the data to the formula, we have:-

Ai = 2 * π * R * H

80 = 2 * 3.14 * 4 * H

80 = 25.12 H

25.12 H = 80

H = 80 / 25.12

H = 3.18

H ≈ 3.2

= 3.2 inches.
