question
the diameter of a circle is 6 ft. find the circumference to the nearest tenth.

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 \( d = 6 \) ft. Substituting this into the formula, we get \( C=\pi\times6 \). Using \( \pi\approx3.14159 \), we have \( C\approx3.14159\times6 = 18.84954 \) ft.

Step3: Round to the nearest tenth.

To round \( 18.84954 \) to the nearest tenth, we look at the hundredth place, which is 4. Since 4 is less than 5, we round down. So, \( 18.84954\approx18.8 \) ft.

Answer:

The circumference of the circle is approximately \( 18.8 \) feet.
