What is the radius of a circle if the area is 7850?

Answer 1

To find the radius of a circle given its area, you can use the formula A = πr^2, where A is the area and r is the radius. In this case, if the area is 7850, you would set up the equation as 7850 = πr^2. To solve for r, you would divide both sides by π and then take the square root, giving you the radius of the circle.

Answer 2

The equation for the area A of a circle is A = pi*r2, where r is the radius of the circle. If you plug in 7850 for the area, you get pi*r2 = 7850. Assuming pi = 3.14, the equation then simplifies to r2 = 7850/3.14 = 2500. Taking the square root of both sides gives you the radius r as 50.
