Question

the diameter of a circle is 6.8 feet. what is the circles circumference?

round your answer to the nearest hundredth.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

We are given that \( d = 6.8 \) feet. Substitute this into the formula: \( C=\pi\times6.8 \).

Step3: Calculate the value

Using \( \pi\approx3.14159 \), we have \( C = 3.14159\times6.8 \approx 21.362812 \).

Step4: Round to the nearest hundredth

Rounding \( 21.362812 \) to the nearest hundredth gives \( 21.36 \).

Answer:

\( 21.36 \) feet
