Answer:

471 in²

Step-by-step explanation:

The surface area of the cylinder is the addition of twice the area of the base and the perimeter of both base and height. This can be expressed as

Given r=5in

But diameter=2× radius

= (5×2)=10inch which is equal to the height.

Area= 2πr +2πr^2

r= radius of the cylinder

h= height of the cylinder

π=3.14

If we input the given values we have,

Area= [2×π×5 ×(2 ×5) + 2 ×π×5 ^ 2]

Area = 471 in²

Hence, the surface area of the cylinder is 471 in²
