Answer:
396
Step-by-step explanation:
circumference of a circle is 2 x pi x r = 2 x 63 x (22/7) = 396
Given:
Radius of the cylinder = 5 in
Height of the cylinder = 30 in.
To find:
The surface area of the cylinder.
Solution:
The surface area of the cylinder is:

Where, r is the radius and h is the height of the cylinder.
Putting
in the above formula, we get




Therefore, the surface area of the cylinder is 1099 square inches.
