Area = Pi(r)2 - A circle with a radius of 25 inches has an area of 1,963.5 square inches.
Area = pi R2 = 25 pi = 78.54 square inches(rounded)
pi*25 = 78.5.
A circle with a circumference of 25 inches has a radius of about 3.979 inches.
Radius = 1/2 (diameter) = 25 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
pi*25 = 78.5.
A circle with a circumference of 25 inches has a radius of about 3.979 inches.
If: pi*radius2 = 25 Then: radius = square root of (25/pi) = 2.821 inches rounded to 3 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)
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
12.5 inches
Radius = 1/2 (diameter) = 25 inches.
The answer is 50 inches.
The area would be 78.53 squared inches. Formula: PI (x) Radius squared = Area Radius is half of the diameter of the circle. So the radius is 5 Inches. (10 divided by 2 = 5) 3.14 x 5 squared = Area ---> 3.14 x 25 = 78.53981634 Hope that helped
