Question

find the diameter of a circle with a circumference of 63 feet. round your answer to the nearest hundredth.
the diameter is about □ feet.

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = \pi d$, where $C$ is circumference and $d$ is diameter.

Step2: Rearrange to solve for $d$

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

Step3: Substitute $C=63$ and calculate

Substitute the given circumference: $d = \frac{63}{\pi} \approx \frac{63}{3.1416}$

Step4: Compute and round to nearest hundredth

Calculate the value: $\frac{63}{3.1416} \approx 20.05$

Answer:

20.05
