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

Answer 1

The circumference of a circle is given by the formula C = 2πr, where C is the circumference and r is the radius.

Using the given radius of 2.5 feet and estimating π as 3.14, we can calculate the circumference as:

C = 2πr
C = 2 * 3.14 * 2.5
C ≈ 15.7 feet

Therefore, the estimated circumference of the circle is 15.7 feet (rounded to the tenths place).
