Question

the diameter of a circle is 55 in. find the circumference to the nearest whole number. answer attempt 1 out of 2 c = in

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute the given diameter

Given $d = 55$ in, so $C=\pi\times55$.

Step3: Calculate the value

Taking $\pi\approx3.14$, we have $C\approx3.14\times55 = 172.7$.

Step4: Round to the nearest whole number

Rounding $172.7$ to the nearest whole number gives $173$.

Answer:

$173$
