Question

The oval track below is formed by a straight section on each side and a semicircle at each end. What is the approximate distance around the track?

Answer 1

1,040 feet

is the answer

Answer 2

1040 feet

Explanation:

The oval track is formed by two straight sides and two lengths of the circumference of a semicircle. The two semicircles forms a circle, so that:

The length of the circumference of a circle = 2πr

The approximate distance around the track = 300 + 300 + 2πr

= 600 + 2×(22/7) × 70

= 1040

The approximate distance around the track is 1040 feet.
