Answer:
Circumference of required circle = 27.0021 feet.
Solution:
Given that area of circle = 58 square feet
We need to find the circumference
Circumference of circle = [tex]2\pi r[/tex] where r is radius.
We don’t have radius in given information but we do have area of circle.
So first need to calculate radius of a circle from given area.
[tex]Area of circle = \pi r^{2}[/tex]
where “r” is radius of circle.
[tex]58=\pi r^{2}[/tex]
[tex]r^2= (58 \times 7)/22=18.4545[/tex]
So we get
r = square root of 18.4545 = 4.2958 feet
Circumference of circle = [tex]2 \mathrm{\pi r}[/tex]
= 2 [tex](\frac{22}{7})[/tex] (4.2958) = 27.0021 feet.
Hence circumference of required circle = 27.0021 feet.
