If the lateral surface area of a cylinder is 94.2 sq cm and its height is 5 cm, then find the radius of its base. (n = 3.14)


A) 5 cm

B) 8 cm

C) 3 cm

D) 4cm

Correct Answer:
C) 3 cm

Description for Correct answer:

Given, lateral surface area = 94.2 sq. cm.

=> \( \Large 2 \pi rh = 94.2 \)

Therefore, \( \Large r = \frac{94.2}{2 \times 3.14 \times 5} = 3 cm \)
