What is the circumference of a circle with a diameter of 4.5 miles? Estimate the circumference to the hundredths place using 3.14 for π.

1. 63.59 miles
2. 7.07 miles
3. 14.2 miles
4. 14.13 miles

1 answer

The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.

Given a diameter of 4.5 miles, we can substitute this value into the formula:

C = 3.14 x 4.5
C ≈ 14.13 miles

Therefore, the correct answer is option 4. 14.13 miles.
