Question

The radius of a circle is 3 inches. What is the circle's circumference?r=3 inUse 3.14 for a.inches

Answer 1

The circumference of the circle is 18.84 inches.

Step-by-step explanation:

The circumference of a circle can be found using the formula C = 2πr, where r is the radius of the circle.

Given that the radius of the circle is 3 inches, we can substitute this value into the formula:

C = 2(3.14)(3) = 6.28(3) = 18.84 inches.

Therefore, the circle's circumference is approximately 18.84 inches.

Answer 2

The circumference of the circle can be calculated as:

`C=2\pi\cdot r`

If we have a radius of r=3, the circumference C is:

`\begin{gathered} C=2\pi r \\ C=2\cdot3.14\cdot3 \\ C=18.84 \end{gathered}`

The circumference of the circle is 18.84 inches.
