Question

part 2: answer the following word problems. use 3.14 for π. 1. the radius of a circle is 11.7 meters. calculate the circumference of the circle. round your answer to the nearest tenth.

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 $r = 11.7$ and $\pi = 3.14$ into the formula:
$C = 2 \times 3.14 \times 11.7$

Step3: Calculate intermediate product

First compute $2 \times 3.14 = 6.28$

Step4: Compute total circumference

$C = 6.28 \times 11.7 = 73.476$

Step5: Round to nearest tenth

Round 73.476 to the nearest tenth: $73.5$

Answer:

73.5 meters
