Hello!
To find the surface area of a cylinder, we use the formula: SA = 2πrh+2πr².
In the description given, the radius is equal to 6 inches and the height is 15 inches. With those values, we can find the surface area by substitution.
SA = 2π(6)(15) + 2π(6)²
SA = 2π(90) + 2π(36)
SA = 180π + 72π
SA = 252π
In terms of pi, the surface area of the cylinder is 252π inches.
