Using perimeter formula 2 x π x r = 44 with π = 22/7, we get 2 x (22/7) x r = 44. Dividing both sides by 44/7 gives radius r = 7 cm.

Let the radius of the circle be r cm.
Given circumference = 44 cm.
The formula for the perimeter of a circle is: Circumference = 2 x π x r
Substitute π = 22/7: 44 = 2 x (22/7) x r 44 = (44/7) x r
Multiply both sides by 7 and divide by 44: r = (44 x 7) / 44 r = 7 cm.
Therefore, the radius of the circle is 7 cm.
