You cannot SOLVE a circle. You can find the radius of a circle, or its diameter, or circumference or area. Or you can find the equation of a circle in the Cartesian system or in polar coordinates. Or find other characteristics of the circle.

In any case, a circle cannot have an area of 24 centemeter. Apart from the fact that there is no such word - try centimetre (or centimeter). A centimetre is a measure of length, not area.

You use the information you're given, along with the facts and formulas you know about the geometry of a circle.

Use the formula for the area of a circle: area = pi x radius2 Replace the data you know (in this case the area), and solve for the unknown (in this case the radius).

Area of a circle = (pi) (radius)2 Radius = 1/2 (diameter) = 12. Area = (pi) (12)2 = 144 pi = 452.389 square units (rounded)

The formula for finding the area of any circle is pi*radius2..

The area of a circle is given by the equation A=πr2.To solve for r, divide both sides by π, then take the square root of both sides of the equation.This leaves you with the equation r=sqrt(A/π)

You can certainly express the radius as a function of its area, yes. If the area is known, you can solve the formula for the area of the circle to uniquely get the radius. (The quadratic equation has two solutions; you will of course choose the positive solution for the radius.)
