Answer:
diameter: 240 ft
radius: 120 ft
circumference: 240π ft or 753.98ft
Explanation:
14,400π ft^2 is the area and you find the area of a circle using the equation
πr^2
if you write that πr^2 = 14,400π ft^2, then you can solve for the radius
divide each side by π and then put the 14,400 into a radical
you will get the answer 120 meaning that your radius is 120 ft.
Radius is one half of the diameter so just multiply 120 by 2 to get a diameter of 240 ft
finally, the formula for the circumference of a circle is 2πr
we know that the radius is 120 so we plug it in: 2(π)(120)
the answer you get is 240π or about 753.98 ft
hope this helps :)
