Question

find the circumference of $odot c$. round your answer to the nearest hundredth.
7.5 m
the circumference is about $\boldsymbol{square}$ meters.

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 radius value

The radius $r = 7.5$ m. Substitute into the formula:
$C = 2\pi \times 7.5$

Step3: Calculate and round

First compute $2\times7.5=15$, so $C = 15\pi$. Calculate the numerical value: $15\times3.14159\approx47.12$

Answer:

47.12
