Question

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 point)
15.7 feet
15.6 feet
16 feet
7.85 feet

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius of the circle.

Step2: Substitute the given values into the formula

We are given that \( r = 2.5 \) feet and \( \pi = 3.14 \). Substituting these values into the formula, we get:
\( C = 2\times3.14\times2.5 \)
First, calculate \( 2\times2.5 = 5 \). Then, multiply this result by \( 3.14 \): \( 5\times3.14 = 15.7 \)

Answer:

A. 15.7 feet
