Question

a circle has a diameter of 10 yd. what is its circumference? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle when the diameter \( d \) is known is \( C=\pi d \).

Step2: Substitute the given values

We know that \( d = 10 \) yd and \( \pi=3.14 \). Substituting these values into the formula, we get \( C = 3.14\times10 \).

Step3: Calculate the result

\( 3.14\times10 = 31.4 \). The unit for circumference is yards (yd) since it is a linear measurement.

Answer:

\( 31.4 \) yd
