Question

find the diameter of circle a. you can use your zearn calculator to help you solve. you may consider writing your answer to the hundredths place.

	diameter (in)	circumference (in)
circle b	7	?
circle c	6	?

Explanation:

Step1: Recall circle - formula

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

Step2: Solve for diameter

We know that for Circle A, $C = 10$. Rearranging the formula $C=\pi d$ to solve for $d$, we get $d=\frac{C}{\pi}$. Substituting $C = 10$ into the formula, we have $d=\frac{10}{\pi}$.

Step3: Calculate the value

Using a calculator, $d=\frac{10}{\pi}\approx3.18$ (rounded to the hundredths place).

Answer:

$3.18$
