Question
If the circumference of a circle is 154 cm then find the
area of the circle?Solution
Let the radius of a circle = (r) cm Circumference of circle = 2πr According to the question ⇒ 2 x π x r = 154 ⇒ 2 x (22/7) x r = 154 ⇒ r = (154 x 7)/(22 x 2) ⇒ r = 24.5 cm Area of circle = πr2 Area of circle = 22/7 x 24.5 x 24.5 Area of circle = 1886.5 cm2
