The circumference of a circle Is 44 m. Find area of circle. |
|
Answer» Given Circumference = 44 m Let radius of circle = r m Thus, 2πr = 44 ⇒ 2 × \(\frac { 22 }{ 7 }\) × r = 44 ⇒ r = \(\frac { 44\times 7 }{ 2\times 22 } \) = 7 m Area of circle = πr2 = \(\frac { 22 }{ 7 }\) × 7 × 7 = 154 m2 Thus, area of circle is 154 m2 |
