Sagot :
Area of a circle = πr^2
Circumfrance of a circle = 2πr or πd
If 15 ft is the circumfrance, then
15 ft = 2πr
So, 15/2π = r
Now that r is known, just plug it in/substitute it in to the formula for the circle.
A = (π)(15/2π)(15/2π)
A = 225/4π = 56.25π
Use a calculator.

Use a calculator.
area= r^2 x pi
pi= 3.14
C= 2 r x pi
15= 2r x 3.14
15/3.14= 2r
4.78= 2r
2,39 = r
A= 2.39 x 2.39 x 3.14=
A= 17.94 square feet
