Question

the diameter of a circle is 13 m. find the circumference to the nearest tenth.

Explanation:

Step1: Recall the formula for circumference

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

Step2: Substitute the given diameter

Given \( d = 13 \) m, substitute into the formula: \( C=\pi\times13 \).

Step3: Calculate the value

Using \( \pi\approx3.14159 \), we get \( C = 13\times3.14159\approx40.84067 \).

Step4: Round to the nearest tenth

Rounding \( 40.84067 \) to the nearest tenth gives \( 40.8 \).

Answer:

The circumference of the circle is approximately \( 40.8 \) meters.
