we are given
circle
[tex] Area=144\pi ft^2 [/tex]
Let's assume
diameter=d
now, we can find expression for area
[tex] A=\frac{1}{4} \pi d^2 [/tex]
now, we can plug values
[tex] 144 \pi =\frac{1}{4} \pi d^2 [/tex]
now, we can solve for d
[tex] d^2=144*4 [/tex]
[tex] d=24 [/tex]
so, diameter is 24 feet...........Answer
