question
the diameter of a circle is 73 cm. find the circumference to the nearest whole number.

Explanation:

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle with diameter \( d \) is \( C = \pi d \).

Step2: Substitute the diameter value

Given \( d = 73 \) cm, substitute into the formula: \( C=\pi\times73 \). Using \( \pi\approx3.1416 \), we get \( C\approx3.1416\times73 \).

Step3: Calculate the value

\( 3.1416\times73 = 229.3368 \).

Step4: Round to nearest whole number

Rounding \( 229.3368 \) to the nearest whole number gives \( 229 \).

Answer:

229
