Question

the diameter of a circle is 11.8 inches. what is the circles circumference?
d=11.8 in
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 know that \( d = 11.8 \) inches and we use \( \pi\approx3.14159 \). So we substitute \( d \) into the formula: \( C=\pi\times11.8 \).

Step3: Calculate the value

\( C = 3.14159\times11.8\approx37.07 \) (rounded to the nearest hundredth).

Answer:

\( 37.07 \) inches
