Question

A right circular cylinder is 3m high and the circumference of its base is 22m.Find its CSA....

Answer 1

Answer:

Circumference = 2πr

= 22m

h = 3m

CSA = 2πr * h

= 22 * 3

= 66 m².

Answer 2

Step-by-step explanation:

Let the base cylinder be r cm.

Then ,

2πr=22

r= 7/2

h= 3 cm

Curved surface area of cylinder = 2πrh

                                                     = 2*22/7*7/2*3

                                                     = 66 cm^2 (Answer)
