Question

the diameter of a circle measures 28 cm. 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 circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $C$ is the circumference and $d$ is the diameter.

Step2: Substitute the given values

Given $d = 28$ cm and $\pi=3.14$, we substitute into the formula: $C=3.14\times28$.

Step3: Calculate the result

$3.14\times28 = 87.92$ cm.

Answer:

$87.92$ cm
