Question

if the lateral surface area of a cylinder is 94.2 square centimetre and its height is 5 CM then find the radius of its base​

Answer 1

Given, h=5cm

⇒Let radius =r

Curved Surface Area ⇒94.2cm =2πrh

⇒94.2 cm =2×3.14×r×5cm

⇒r=3cm

Answer 2

✯Given✯

➙ L.S.A of cylinder = 94.2cm²

➙ Height of cylinder = 5cm

✯To find✯

➙ Radius of cylinder

✯Solution✯

→  2πrh = 94.2

→   2 × ²²⁄₇ × r × 5 = 94.2

→  r = 94.2 ÷ 2 × ²²⁄₇ × 5

→  r = 94.2 ÷ 31.4

→  r = 3

✦The radius of cylinder is 3cm✦
