Question 414360
Julie and Tess are running around two separate circular tracks.
 Julie is running around a track with a radius of 12 yards, while Tess is running a track with a radius of 30 yards.
They both decide to sprint. Julie's sprint covers a 45 degree arc, while Tess' sprint covers a 120 degree arc.
 Find the sum of the lengths of the two sprints to the nearest tenth of a yard.
:
Find the circumference of J's track
C = {{{2*pi*12}}}
C = 75.398 yds
Find distance of 45 degree arc
{{{45/360}}} * 75.398 =  9.43 yds
:
Do the same with T's track
C = {{{2*pi*30}}}
C = 188.450 yds
Find distance of 120 degree arc
{{{120/360}}} * 188.450 =  62.83 yds
:
Their sum
9.43 + 62.83 ~ 72.3 yds
