Question 67375
You can use proportions to solve this problem:
{{{x/C = 40/360}}} Where: x = the required distance along the circumference and C = the entire circumference. {{{C = (pi)D}}} and D = 40 ft.
{{{x =40(40(pi))/360}}}
{{{x = 1600(pi)/360}}}
{{{x = 4.44(pi)}}} Using {{{(pi) = 3.14}}} as an approximation.
{{{x = 13.96}}} feet.
