Question

Find the surface area of the net diagram of the right circular cylinder. Use 3.14 for π.
an illustration shows 2 circular cylinders with a rectangle in the middle which is 4 in
the cylinder on the right has 8 in and the left cylinder has 8 inch

Answer 1

Correct

Answer 2

To find the surface area of the net diagram of the right circular cylinder, we need to find the areas of the two circular bases and the rectangle in the middle.

The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh

For the cylinder on the right with a radius of 4 inches and a height of 8 inches:
Surface Area = 2(3.14)(4^2) + 2(3.14)(4)(8)
Surface Area = 2(3.14)(16) + 2(3.14)(32)
Surface Area = 100.48 + 200.96
Surface Area = 301.44 square inches

For the cylinder on the left with a radius of 4 inches and a height of 8 inches:
Surface Area = 2(3.14)(4^2) + 2(3.14)(4)(8)
Surface Area = 2(3.14)(16) + 2(3.14)(32)
Surface Area = 100.48 + 200.96
Surface Area = 301.44 square inches

Therefore, the total surface area of the net diagram of the right circular cylinder is 602.88 square inches.
