Question

The curved surface area of cylinder whose radius 7/2 cm and height 7 cm is

Answer 1

Step-by-step explanation:

radius=7/2cm

height=7cm

csa=2πrh

=2*22/7*7/2*2

=154cm sq

Answer 2

Dear Student,

◆ Answer -

Curved surface area of cylinder = 154 sq.cm

● Explaination -

# Given -

r = 7/2 cm

h = 7 cm

# Solution -

Curved surface area of cylinder is calculated by -

CSA = 2πrh

CSA = 2 × 22/7 × 7/2 × 7

CSA = 22 × 7

CSA = 154 cm^2

Therefore, curved surface area of cylinder is 154 sq.cm.

Thanks dear. Best luck for the exams..
