Question

The circumference of a circle is 25.12 meters. What is the circle's radius?C = 25.12 mUse 3.14 for .meters

Answer 1

Answer: We have to find the radius of the circle, the formula that connects the circumference to the radius is as follows:

`C=2\pi r\Rightarrow(1)`

Plugging in the known information in the equation (1) gives us the answer as follows:

`\begin{gathered} 25.12m=2*3.14* r \\ \\ \therefore\Rightarrow \\ \\ r=(25.12m)/((2*3.14))=4m \\ \\ r=4m \end{gathered}`

Therefore the answer is 4 meters.
