Answer:
Given:- area of circle is 154cm²
- Area of circle = πr²
- Circumference of Circle = 2πr
Now first we need to find radius of circle so we will use the given parameters
=> Area of circle = 154 cm²
=> π × r² = 154 cm²
=> r² = (154 ×7)/22
=> r² = 49
=> r = 7cm
Now, easily we can find the circumference of circle.
=> Circumference of Circle = 2πr
=> 2×(22/7) × 7
=> 44cm
Therefore, circumference of the circle is 44cm
