Question

Volume of Cylinder of height 8 cm is 1232 cm find the curved surface area of cylinder ​

Answer 1

Answer:

352 cm²

Step-by-step explanation:

H = 8cm

Vol. = 1232cm³

22/7 * r² *h = 1232

r² * 8 = 1232*7/22

r² = 56*7/8

r² = 7*7

r² = 7²

So, r = 7

C.S.A. = 2*22/7*r*h

= 2*22/7*7*8

=44*8

=352cm²
