You are asked to build a circular running track of length 1/4 km. To the nearest meter, what would be
the radius of the track? (Recall that 1 km is 1000 m.)
circumf = 2πr
2πr = 250
r = 250/(2π) = 40 m to the nearest m
the radius of the track? (Recall that 1 km is 1000 m.)
2πr = 250
r = 250/(2π) = 40 m to the nearest m
