Question

the radius of a circle is 3.8 m. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius.

Step2: Substitute the given radius

Given $r = 3.8$ m, we substitute it into the formula: $C=2\pi\times3.8$.

Step3: Calculate the value

$C = 2\times3.14\times3.8=23.864$ m.

Step4: Round to the nearest whole number

Rounding $23.864$ to the nearest whole number gives $24$ m.

Answer:

$24$ m
