      Question

      If the circumference of a circle is 220 cm then find the

      area of the circle?
      A 616 cm² Correct Answer Incorrect Answer
      B 346.5 cm² Correct Answer Incorrect Answer
      C 1386 cm² Correct Answer Incorrect Answer
      D 3850 cm² Correct Answer Incorrect Answer

      Solution

      Let the radius of a circle = (r) cm Circumference of circle = 2πr According to the question ⇒ 2 x π x r = 220 ⇒ 2 x (22/7) x r = 220 ⇒ r = (220 x 7)/(22 x 2) ⇒ r = 35 cm Area of circle = πr2 Area of circle = 22/7 x 35 x 35 Area of circle = 3850 cm2
