Question

The diameter of a circle is 8 centimeters. What is the circle's circumference?d=8 cmcentimetersUse 3.14 for л.

Answer 1

Answer: 25.12 cm

The circumference of the circle is solved using the following formula:

`C=2\pi r`

From the problem, we know that:

d = 8cm; r = d/2 = 4cm

π = 3.14

Substitute these to the formula and we will have:

`\begin{gathered} C=2\pi r \\ C=2(3.14)(4\text{ cm}) \\ C=25.12\text{ cm} \end{gathered}`

With this, we know that the circumference of the given circle is 25.12 cm.
