WebWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 … Webthis problem is an application of radical functions. You are asked to express the radius of a circle as a function of its syria. So I have written the formula for the area of a circle. …
