Question

greg installed a circular drain that has a diameter of 4.8 inches. question: to the nearest tenth of an inch, what is circumference of the drain? 7.5 15.1 18.1 30.1

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given $d = 4.8$ inches, then $C=\pi\times4.8$.

Step3: Calculate the value

Taking $\pi\approx3.14$, we have $C\approx3.14\times4.8 = 15.072$.

Step4: Round to the nearest tenth

Rounding $15.072$ to the nearest tenth gives $15.1$.

Answer:

$15.1$
