✬ Radius = 14 cm ✬

Step-by-step explanation:

Given:

Curved surface area of right circular cylinder is 176 cm².

Measure of height of cylinder is 2 cm

To Find:

What is the measure of radius of base ?

Solution: Let r be the radius of cylinder.

As we know that

★ CSA of Cylinder = 2πrh ★

A/q

CSA = 176 cm²

⟹ 176 = 2πrh

\implies{\rm }⟹ 176 = 2(22/7)(r)(2)

\implies{\rm }⟹ 176 = 44/7(2r)

\implies{\rm }⟹ 176 = 88r/7

\implies{\rm }⟹ 176 \times× 7 = 88r

\implies{\rm }⟹ 1232 = 88r

\implies{\rm }⟹ 1232/88 = r

\implies{\rm }⟹ 14 = r

Hence, measure or radius of base of cylinder is 14 cm.
