The circumference of a circle with a radius of 2.5 feet can be calculated using the formula:

C = 2πr

where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius.

Substituting the given values:

C = 2 * 3.14 * 2.5 = 15.7 feet

So the estimated circumference to the tenths place using 3.14 for π is 15.7 feet.
