OMG Test due in like 15 min! A running track in the shape of an oval is shown. The ends of the track form semicircles.

A running track is shown. The left and right edges of the track are identical curves. The top and bottom edges of the track are straight lines. The track has width 54 m and length of one straight edge 120 m.
What is the perimeter of the inside of the track? (π = 3.14) (1 point)

409.56 m
480.00 m
579.12 m
616.80 m

dunno

step-by-step explanation:

78.59 is the mean

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
