Abowling ball has a diameter of 8.5 inches. if it is rolled down a 60-foor bowling lane, how many complete revolutions will it make?

We know that
A bowling lane is 42 inches wide and 60 feet long
1 ft> 12 in
60 ft> X
X=60*12> X=720 in

[the length of a circumference]=2*pi*r
for r=8.5/2> r=4.25 in
[the length of a circumference]=2*pi*4.25>26.69 in

if 26.69 in  represent> 1 revolution
720 in (bowling lane)> X
X=720/26.69> X=26.98  revolution

the answer is
26 revolutions
