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? image of oval track with 140 feet (diameter of semicircles) and 300 feet (length of straight section) 1,340 feet 1,040 feet 440 feet 820 feet

Explanation:

Step1: Identify track components

The track has two straight sections (each 300 ft) and two semicircles (forming a full circle, diameter 140 ft).

Step2: Calculate straight sections length

Two straights: \( 2 \times 300 = 600 \) feet.

Step3: Calculate circle circumference

Circumference formula: \( C = \pi d \), \( d = 140 \), so \( C \approx 3.14 \times 140 = 439.6 \approx 440 \) feet.

Step4: Total track distance

Sum straights and circle: \( 600 + 440 = 1040 \) feet.

Answer:

1,040 feet
