Find the surface area of a cylinder:
r=9 in,h=18 in
  1. 1525.03 in2
  2. 1526.04 in2
  3. 1526.04 in
  4. 1526.04 in3

A
1525.03 in2
B
1526.04 in2
C
1526.04 in
D
1526.04 in3
Solution
Verified by Toppr

The correct option is A 1526.04 in2
Surface area of cylinder is A=2πr(r+h)

Here, radius is r=9 in and the height is h=18 in.

Thus,

A=2πr(r+h)=2×3.14×9(9+18)=56.52×27=1526.04

Hence, the surface area of the cylinder is 1526.04 in2.
