To find the height of the net diagram, we first need to find the total surface area of the right circular cylinder.
The surface area of a right circular cylinder can be calculated using the formula:
Surface Area = 2πr^2 + 2πrh
Where:
r = radius of the base of the cylinder
h = height of the cylinder
In this case, we are given that the surface area of the net diagram is 395.64 ft^2. Since there are two cylinders, we can find the surface area of one cylinder by dividing the total surface area by 2:
395.64 ft^2 / 2 = 197.82 ft^2
Now, we can plug in the values into the formula and solve for the height:
197.82 = 2(3.14)(3)^2 + 2(3.14)(3)h
197.82 = 56.52 + 18.84h
18.84h = 141.30
h = 7.5 feet
Therefore, the height of the net diagram is 7.5 feet.
