I'm not completely sure what a "2.5 inch circle" is. Is that the distance all the way across the circle (diameter), or is it the distance from the center of the circle to its curve (radius) ? If diameter = 2.5 inches, then area = 4.909 square inches If radius = 2.5 inches, then area = 19.635 square inches
The area of a circle with an 8 inch diameter is approximately 50.27 square inches.
