⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐
Given, circumference of circle = 22 cm.
Also, we know circumference = 2πr (where, π = 22/7 and r means radius)
So, 2πr = 22
=> 2 × (22/7) × r = 22
=> 44/7 × r = 22
=> r = (22×7/44) cm = 3.5 cm
So, radius of that circle = 3.5 cm.
Now, Area of circle= πr²
= ((22/7)×(3.5)²) cm²
= ((22/7)×12.25) cm²
= (22 × 1.75) cm²
= 38.5 cm² (Required Answer)
