The surface area of the cylinder with the given height and radius is 835.2 square inches
How to determine the surface area?
The given parameters are
- Height, h = 12 inches; this is represented by the distance between the curved surfaces of the cylinder
- Radius, r = 7 inches; this is represented by the distance between the center of the circle to its circumference
The surface area is then calculated using the following formula
A = 2πr² + 2πrh
Substitute the given values in the above equation
So, we have:
A = 2 * 3.14 * 7^2 + 2 * 3.14 * 7 * 12
Evaluate the exponents
A = 2 * 3.14 * 49 + 2 * 3.14 * 7 * 12
Evaluate the products
A = 307.72 + 527.52
Evaluate the sum
A = 835.2
Hence, the surface area of the cylinder with the given height and radius is 835.2 square inches
