Area = 64pi implies that radius = 8 units
So diameter = 2*rad = 16 units.

64pi (miles square)
The area of a circle whose diameter is 18 inches is: 254.5 square inches.
The area of a circle can be found with the formula (pi)r2. Since r = d/2, r would be 8in in this case. A = 64pi in2, or 201.1in2
A diameter is a line, and has no area.A circle whose diameter is 8.5 has an area of 56.745. (rounded)
