WebArea of a circle with radius r is given as π × r 2. Given that r = 7 c m. By the formula, Area = π × 7 2. ⇒ Area = 22 7 × 7 × 7 ∵ π ≈ 22 7. ⇒ Area = 22 × 7. ⇒ Area = 154 C m 2. Hence, area of a circle with radius 7 C m is 154 C m 2. Suggest Corrections. 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.
