A circle with an 8-inch diameter has a perimeter of 25.1 inches.
The apostrophe in 7' means 7 inches. This means that there would be two 7 inch sides to the rectangle and two 8 inch sides. Perimeter = 7+7+8+8= 30 inches.
I believe 8 feet 6 inch radius and 8 feet 6 inch is 8.5 feet Area of circle is pi x radius x radius = pi x 8.5 x 8.5 = 226.98 square feet

Radius = diameter/2 so 16/2 = 8 inches.
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
half of 16 = 8 inches
