Question

Find the total surface area of a cylinder of base radius 5cm and length 7cm (π = 3.14)

Options

A) 219.9cm2

B) 157.1cm2

C) 377.0cm2

D) 298.7cm2

The correct answer is C.

Explanation:

The total surface area of a cylinder = 2πrl + 2πr2
= 2πr(l + r)
= 2 × 3.14 × 5 (7 + 5)
2 × 3.14 × 5 * 12
= 377.0 cm2 (to 1 decimal place)
