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 circumference formula

$C = \pi d$ (where $C$ is circumference and $d$ is diameter)

Step2: Substitute values

Given $d = 28$ cm and $\pi=3.14$, so $C=3.14\times28$

Step3: Calculate result

$C = 87.92$ cm

Answer:

$87.92$ cm
