I REALIZED I DID IT WRONG SO UH IGNORE WHAT I SAID IM SORRY D:
Let's break it down, there's 24 hours in a day and there's 60 minutes for each hour so there are 1440 minutes are in a day. (60 * 24)
For
c=ax+by
the slope is -a/b
given
-48=2x-8y
slope=-2/-8=-1/-4=1/4
slope=1/4
C=2(3.14)r Where C is the circumference, and r the radius. Here you give the radius, which is 15, so it will be C=2(3.14)(3) C=18.84ft
