The formula for the circumference of a circle is C = 2πr, where r is the radius.
Plugging in the given radius of 2.5 feet and using 3.14 for π, we can estimate the circumference:
C = 2 * 3.14 * 2.5
C ≈ 15.7 feet
Therefore, the estimated circumference to the tenths place is 15.7 feet. Hence, the correct option is 2.
What is the circumference of a circle with a radius of 2.5 feet? Estimate the circumference to the tenths place using 3.14 for π.
1. 7.85 feet
