The area of any circle can be found by the formula [tex] A=\pi r^{2} [/tex]
That is :Square the radius and multiply by pi to find the area of the circle.
Here r denotes the radius of the circle .[tex] \pi [/tex] has a fixed value.
In the question radius is given as 15 ft.Substituting r with 15 ft in the area of circle we have:
A= [tex] \pi 15^{2} [/tex]
A=[tex] \pi .225 [/tex]
A= 706.85.
A=706.9( Rounded to one decimal place)
Approximate area of circle with radius 15 ft is 706.9 square ft,
First option is the right answer.
