Radius of 7cm
WebAs we know, the area of circle is equal to pi times square of its radius, i.e. π x r 2. To find the area of circle we have to know the radius or diameter of the circle. For example, if the radius of circle is 7cm, then its area will be: Area of circle with 7 cm radius = πr 2 = π(7) 2 = 22/7 x 7 x 7 = 22 x 7 = 154 sq.cm.
