Question

6 find the diameter of the circle if its circumference measures 31.4 units.

Explanation:

Step1: Recall circumference formula

The circumference $C$ of a circle is $C = \pi d$, where $d$ is the diameter, and we use $\pi \approx 3.14$.

Step2: Rearrange for diameter

Isolate $d$: $d = \frac{C}{\pi}$

Step3: Substitute given values

Substitute $C=31.4$ and $\pi=3.14$:
$d = \frac{31.4}{3.14}$

Step4: Calculate the result

Perform the division: $d = 10$

Answer:

10 units
