Question

a circles radius is 3 feet. what is the circles circumference? use 3.14 or a calculator button for pi and provide an answer accurate to the nearest tenth. label required

Explanation:

Step1: Recall circumference formula

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

Step2: Substitute given values

Substitute $r = 3$ and $\pi = 3.14$:
$C = 2 \times 3.14 \times 3$

Step3: Calculate and round to tenth

First compute $2 \times 3.14 = 6.28$, then $6.28 \times 3 = 18.84$. Round to the nearest tenth: $18.8$

Answer:

18.8 feet
