Find the surface area of a cylinder with the following dimension:
Height =10 ft.
Radius =2 ft.
  1. 82πft2
  2. 78πft2
  3. 48πft2
  4. 81πft2

A
78πft2
B
81πft2
C
82πft2
D
48πft2
Solution
Verified by Toppr

Surface area of cylinder is A=2πr(r+h)

Here, radius is r=2 ft and the height is h=10 ft.

Thus,

A=2π×2(2+10)=2π×2×12=48π

Hence, the surface area of the cylinder is 48π ft2.
