I’m confused on this one

we are given
circumference is 2.4 miles
and we know that
[tex] C=2\pi r [/tex]
so, we can find r
[tex] 2.4=2\pi r [/tex]
[tex] r=0.38197 [/tex]
now, we can find area
[tex] A=\pi r^2 [/tex]
we can plug values
[tex] A=\pi (0.38197)^2 [/tex]
[tex] Area=0.45836 [/tex]..............Answer
