Question

Find the diameter of a circle with a circumference of 28.26 centimeters. Use 3.14 for π.

Answer 1

The diameter of the circle is 9.0 cm.

`d=9.0\text{ cm}`

Step-by-step explanation:

Given that the circumference of the circle is 28.26 centimeters.

`C=28.26\text{ cm}`

Recall that the formula for the circumference of a circle is;

`\begin{gathered} C=2\pi r=\pi d \\ d=(C)/(\pi) \end{gathered}`

Substituting the given values;

`\begin{gathered} d=\frac{28.26\text{ cm}}{3.14} \\ d=9.0\text{ cm} \end{gathered}`

Therefore, the diameter of the circle is 9.0 cm.

`d=9.0\text{ cm}`
