Question

the diameter of a circle is 40 m. find the circumference to the nearest whole number. answer attempt 1 out of 2 c = m

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 $d = 40$ m, so $C=\pi\times40$.

Step3: Calculate the value

Taking $\pi\approx3.14$, then $C\approx3.14\times40 = 125.6$ m.

Step4: Round to the nearest whole number

Rounding 125.6 to the nearest whole number gives 126 m.

Answer:

126
