Solution
Given :-
Area of circle = 154 cm
Find :-
Circumference of circle
Explanation
Using Formula
Where,
r is radius of circle
According to question,
➡ Area of circle = πr²
➡154 = πr²
➡154 = 22/7 × r²
➡r² = 154 × 7/22
➡r² = 1078/22
➡r² = 49
➡r = √(49)
➡r = 7
Since
Radius of circle will be r = 7 cm
Now, Calculate Circumference of circle.
➡ Circumference of circle = 2πr
[ π = 22/7 ]
➡ Circumference of circle = 2 × 22/7 × 7
➡ Circumference of circle = 44 cm
Hence
Circumference of circle will be = 44 cm
