If the area of a circle is 58 square feet, find the circumference. A. 26.99 ft. B. 22.35 ft. C. 42.5 ft. D. 4.25 ft.
It's answer is option A.
As the area of circle is given which is 58 square feet, we are to find circumference of the circle.
We know that area = π r^2
Where π = 3.14 and r is radius of the circle
So it will become
3.14 x r^2 = 58
r^2 = 58/3.14
r^2 = 18.4713375796
If we take square root of both sides, we get
r = 4.297829403268585 feet
By using this value of r we can find circumference of the circle,
As,
Circumference = 2 π r
It will become
2 x 3.14 x 4.297829403268585
26.99036
Which is very close to the option A.
