Question

Find the area of a circle if the circum ference of the circle is 44cm​

Answer 1

Answer:

⇒ Circumference of circle =44cm [ Given ]

⇒ Circumference of circle =2πr

⇒ 44=2×22/7 ×r

⇒ r= 44/44 ×7

=7cm

⇒ Area of circle =πr^2

⇒ Area of circle = 22/7 ×(7)^2

⇒ Area of circle =22×7

∴ Area of circle =154cm
