To find the surface area of the net diagram of the right circular cylinder, we need to find the surface areas of the two circles and the rectangle separately and then add them together.
The surface area of a circle is calculated using the formula: A = πr^2
For each circle (radius = 8 inches):
A = 3.14 * 8^2
A = 3.14 * 64
A = 200.96 square inches
The surface area of the rectangle is calculated using the formula: A = length * width
A = 4 * 8
A = 32 square inches
Now, add the surface areas of the two circles and the rectangle:
200.96 + 200.96 + 32 = 433.92 square inches
Therefore, the surface area of the net diagram of the right circular cylinder is 433.92 square inches.
Use the image to answer the question.
An illustration shows a horizontal rectangle of height 4 inches with a circle of radius 8 inches attached to its top left and a circle of radius 8 inches attached to its bottom right.
Find the surface area of the net diagram of the right circular cylinder. Use 3.14 for π.
