Question

the radius of a circle is 5.9 cm. find the circumference to the nearest tenth.

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference \( C \) of a circle is \( C = 2\pi r \), where \( r \) is the radius.

Step2: Substitute the given radius

Given \( r = 5.9 \) cm, substitute into the formula: \( C = 2\times\pi\times5.9 \).

Step3: Calculate the value

First, calculate \( 2\times5.9 = 11.8 \). Then, \( C = 11.8\pi \). Using \( \pi\approx3.1416 \), we get \( C\approx11.8\times3.1416 \approx 37.1 \) (rounded to the nearest tenth).

Answer:

The circumference of the circle is approximately \( 37.1 \) cm.
