Question

A circular jogging track is being designed so that one complete lap around the track is one mile long. What should the radius of the track be to the nearest foot?
(one mile equals five thousand two hundred eighty feet)

two thousand six hundred forty feet

one thousand seven hundred sixty feet

one thousand six hundred eighty-two feet

eight hundred forty-one feet

Answer 1

well if the circumference is 5280 then wouldnt you do 5280=piD, or 5280=2piR?
so if you did that you would solve for D then divide it by 2, or solve for R

Answer 2

So.. 1.57?

Answer 3

i got 840.34

Answer 4

ok.

Answer 5

:)

Answer 6

so 841?

Answer 7

no 840.34 i

Answer 8

then what's the answer?

Answer 9

840.34 lol i did 5280=piD then divided 5280 by pi and then divided that number by 2 to get the radius

Answer 10

OK.
