Given:
Area of circle = 616m²
Find:
Circumference of the circle
Solutions:
Let the radius of the circle be 'r' m.
We know that;
Area of circle = πr²
=> πr² = 616
=> 22/7 × r²
=> r² = 616 × 7/22
=> r² = 56/2 × 7
=> r² = 28 × 7
=> r² = 196
=> r² = √196
=> r = 14m
Now,
Circumference = 2πr
=> 2 × 22/7 × 14
=> 2 × 22 × 7
=> 88m
Hence, the circumference of the circle is 88m.
I hope it will help you.
Regards.

Answer:
=> (4x + 6)/(5x + 6) = 6/7
=> 7(4x + 6) = 6(5x + 6)
=> 28x + 42 = 30x + 36
=> 28x - 30x = 36 - 42
=> -2x = -6
=> x = -6/-2
=> x = 3
