Question

1. the circumference of a circle is 37.68 inches. calculate the diameter of this circle

Explanation:

Step1: Recall circumference formula

The circumference $C$ of a circle is $C = \pi d$, where $d$ is the diameter. We rearrange to solve for $d$: $d = \frac{C}{\pi}$

Step2: Substitute given value

Use $C = 37.68$ inches and $\pi \approx 3.14$
$d = \frac{37.68}{3.14}$

Step3: Calculate the diameter

Perform the division: $37.68 \div 3.14 = 12$

Answer:

12 inches
