question
the diameter of a circle is 56 cm. find the circumference to the nearest whole number.
answer

Explanation:

Step1: Recall the formula for the circumference of a circle

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

Step2: Substitute the given diameter into the formula

We are given that the diameter \( d = 56\) cm. Substituting this into the formula, we get \( C=\pi\times56 \). Taking \( \pi\approx3.14 \), we have \( C = 3.14\times56 \).

Step3: Calculate the value

\( 3.14\times56 = 175.84 \).

Step4: Round to the nearest whole number

Rounding \( 175.84 \) to the nearest whole number gives \( 176 \).

Answer:

176
