Question

The curved surface area of a cylindrical pipe whose circumference is 15 cm and height is 6 cm is ________ cm​

Answer 1

Step-by-step explanation:

Circumference of the base = 15cm².

2×22/7×r=15

r=15×7/22×1/2

r=2.38cm

Now,

CSA of cylinder = 2×22/7×r×h

2×22/7×2.38×6

89.76cm²

Hence, The required curved surface area of the cylinder is 89.76cm².
