Question

The circumference of the base of cylinder is 44 cm and its height is 10 cm , then its curved surface area is​9​

Answer 1

Step-by-step explanation:

2pie r = 44

2 x 22/7 x r = 44

r = 44 x 7 / 22 x 2

r = 7

hieght of cylinder is 10

csa = 2pie r h

csa = 2 x 22 / 7 x 7 x 10

csa = 22 x 2 x 10

csa = 440 cm ^2

Answer 2

Hello Bro!!!

Your answer with step by step explanation is mentioned below.

Step-by-step explanation:

Curved surface area of of a cylinder is given by

$2\pi rh$

But 2πr is the circumference (c) of the circular base.

Hence, 2πr= c (circumference)

So, Curved Surface Area is also given by:

$ch$

where, c is the circumference of the circular base and is given by 2πr

Now as c is 44 cm and h (height) is 10 cm

CSA = 44cm × 10 cm= 440 cm², AND THAT'S THE ANSWER!!!
