Question

PLEASE HELP
Each edge of the winding walkway in the diagram is made of two circular arcs with a radius of 25 feet. The radius is depicted by a dashed line. If the width of the walkway is 5 feet, what is the difference of the lengths of the two edges of the walkway?

so this is a double double question...

but what you have to do is find the arc length. the formula is

\[l = r \times \theta\]

l = arc length, r = radius and \[\theta = the ~sector~Angle~In~~radians\]

so for the 1st part, the sector angle is 1.32 the radii are outer arc 30 ft inner arc 25ft

then when you move to the lower arcs..

sector angle = 1.57 arc length inner = 25 outer arc = 30

so the lengths

you need to add the upper outer arc(30 ft) to the lower inner arc(35 ft)...

then the other edge of the path is

upper inner arc (25 ft) + lower outer arc (30ft)

the answer you need is the difference in the 2 lengths..

I haven't calculated it... just given a method
