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