csa of cylender =2πrh
2πrh=176
πrh=88
22/7.r.21=88
3r=4
r=4/3
so diamete=2r
so 2.4/3=8/3

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.
