Question

a circle has a circumference of 89π centimeters. what is the diameter, in centimeters, of the circle? question 13 of 22 math - module1

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: Solve for the diameter

Given $C = 89\pi$. Substitute into the formula: $89\pi=\pi d$. Divide both sides by $\pi$. So $d = 89$.

Answer:

89
