Question

the diameter of a circle is 69 ft. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula

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

Step2: Substitute the value of diameter

Given $d = 69$ ft, so $C=\pi\times69$.

Step3: Calculate the value

Taking $\pi\approx3.14$, we have $C\approx3.14\times69 = 216.66$ ft.

Step4: Round to the nearest whole number

Rounding $216.66$ to the nearest whole number gives $217$ ft.

Answer:

$217$ ft
