the diameter of a circle is 134 cm. find the circumference to the nearest whole number.

Explanation:

Step1: Recall the formula

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

Step2: Substitute the value

Given $d = 134$ cm, so $C=\pi\times134$.

Step3: Calculate the result

$C\approx3.14\times134 = 419.76$ cm.

Step4: Round to the nearest whole number

Rounding $419.76$ to the nearest whole number gives $420$ cm.

Answer:

$420$ cm
