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). multiple choice options: 440 feet, 820 feet, 1,340 feet, 1,040 feet

Explanation:

Step1: Calculate circle circumference

The two semicircles form a full circle with diameter 140 ft. Circumference: $C = \pi d = \pi \times 140 \approx 439.8$ ft.

Step2: Calculate total straight length

Two straight sections each 300 ft: $2 \times 300 = 600$ ft.

Step3: Sum for total distance

Add circle circumference and straight length: $439.8 + 600 \approx 1039.8$ ft.

Answer:

D. 1,040 feet
