Use the image to answer the question.
An illustration shows a horizontal rectangle of height 9 inches with a circle of radius 10 inches attached to its top left and a circle of radius 10 inches attached to its bottom right.

The surface area of a right circular cylinder can be calculated using the formula:
Surface area = 2πr^2 + 2πrh
In this case, the radius of the circles is 10 inches and the height of the rectangle is 9 inches.
Surface area = 2 * 3.14 * 10^2 + 2 * 3.14 * 10 * 9
Surface area = 2 * 3.14 * 100 + 2 * 3.14 * 10 * 9
Surface area = 628 + 565.2
Surface area = 1193.2
Therefore, the surface area of the net diagram of the right circular cylinder is 1193.2 square inches.
