Question
If the circumference of a circle is 44 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 = 44 ⇒ 2 x (22/7) x r = 44 ⇒ r = (44 x 7)/(22 x 2) ⇒ r = 7 cm Area of circle = πr2 Area of circle = 22/7 x 7 x 7 Area of circle = 154 cm2
