12.5 inches

The answer is 50 inches.

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

Radius of circle: 25/2 = 12.5 feet

The diameter of a circle with a circumference of 25 inches is: 78.54 inches. (d = c divided by Pi).

The circumference of a circle with a radius of 12.5 is 78.54 to two decimal places.

Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)

Radius of circle: 25/2 = 12.5 feet

25. The answer also depends on the unit of measurement (feet, inches, centimeters, etc.)

Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet

A circle with a circumference of 25 inches has a radius of about 3.979 inches.

Radius = 1/2 of the diameter = 12.5 cm.

50 cm is the diameter.
