A)12,566 feet
B)1,047 feet
C)5,236 feet
D)9,196 feet

Answer 1

Answer: B)1,047 feet

Explanation:

Hi, to answer this question, first, we have to calculate the circumference of the tire:

Circumference(C): π x diameter

C = π (20) = 62.83 inches.

Since 1 foot is equal to 12 inches.

62.83 ÷ 12 = 5.23 feet

Finally we have to multiply the result by 200:

5.23 x 200 = 1,047 feet
