The area of a circle, if the radius is 5 cm, is: 78.54 cm2
Well, darling, if the area of the circle is 25π cm², then we can use the formula A = πr² and plug in the area to solve for the radius. So, 25π = πr², which means the radius is 5 cm. Voilà, problem solved!
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
58.875 units squared
Radius = diameter/2 = 5 cm
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
