Question

1. if the circumference of a circle is 106.76 meters, what is the radius?

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $C$ is circumference, $r$ is radius, and we use $\pi \approx 3.14$.

Step2: Rearrange to solve for $r$

Isolate $r$ by dividing both sides by $2\pi$:
$r = \frac{C}{2\pi}$

Step3: Substitute given value

Substitute $C = 106.76$ meters and $\pi \approx 3.14$:
$r = \frac{106.76}{2 \times 3.14} = \frac{106.76}{6.28}$

Step4: Calculate the result

Perform the division:
$r = 17$

Answer:

17 meters
