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 56 m and length of one straight edge 130 m.
(see attachment)

what is the perimeter of the inside of the track?

a: 260.00 m
b: 347.92 m
c: 372.00 m
d: 435.84 m

The two ends of the track are semi circles, so we need to calculate the circumference:

Circumference = PI x 56 = 175.84

The two straight  parts are 130 m each:

Total perimeter = 175.84 + 130 + 130 = 435.84 m

The answer is D.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
