    Area of circle with radius r units = p*r^2*units^2. Here unit = ft and r = 5 giving

    area of pi*(5ft)^2 = 25pi*ft^2;

    The radius of the circle is 5 feet.

    Area is πr² = 25π

    i.e. r² = 25

    Hence, r = 5 feet

    If the area of a circle is 25 pi ft^2, 

    the radius of the circle is 5 ft.

    Radius of the circle = 5 ft because area is pi'*5^2 = 25*pi square feet

    A= πr²= 25π; r= 5
