Question

the diameter of a circle is 150 ft. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula for circumference.

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

Step2: Substitute the given diameter.

Given $d = 150$ ft, so $C=\pi\times150$.

Step3: Calculate the value.

Taking $\pi\approx3.14159$, then $C\approx3.14159\times150 = 471.2385$ ft.

Step4: Round to the nearest whole number.

Rounding $471.2385$ to the nearest whole number gives $471$ ft.

Answer:

$471$ ft
