Question

the diameter of a circle measures 10 mm. what is the circumference of the circle? 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 the circumference of a circle

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

Step2: Substitute the given values into the formula

We are given that the diameter \( d = 10\space\text{mm} \) and \( \pi=3.14 \). Substituting these values into the formula, we get \( C = 3.14\times10 \).

Step3: Calculate the result

\( 3.14\times10=31.4 \). So the circumference of the circle is \( 31.4\space\text{mm} \).

Answer:

\( 31.4\space\text{mm} \)
