Question

The volume of a cylinder of height 8 cm is 1232 cm2. Find the curved surface area and the total surface area

Answer 1

Answer:

Step-by-step explanation:

Volume of cylinder =pie*r*h=1232cm^2

R^2=1232 divided by 8 *7/22 .

R= Square root of 49 =7

C.s.a= 2*pie* r *h

2*22/7*7*8=352cm^2

Lsa = 2* pie *r(r +h)

2*22/7*7(7+8)

=660cm^2
