Step-by-step explanation:
Let the radius if circle be r
Given, Area of circle = 491 cm²
Area of circle = πr²
π2 = 491
Since =22/7
therefore πr² = 49
• r²= 49
• r = √49 = 7 cm
therefore Radius of circle = 7 cm
Circumference of circle = 2πr
= 2 x π x 7 cm
= 14π cm
therefore Circumference of the circle is 141 cm
