how can you calculate the area of the circle if you know the circle's circumference?

Answer with step-by-step explanation:We know that the formula for area of a circle is given by:Area of a circle = [tex] \pi r ^ 2 [/tex]So to find the area of circle, we basically need to know the radius of the circle.If we know the circumference of the circle, we can calculate the area of the circle too.Formula for the circumference of the circle is given by:[tex]2\pi r[/tex]So if we know the circle's circumference, we can find the value of radius and then find the area of circle with it.
