Question

Find the circumference and the area of a circle with radius 6 m.Use the value 3.14 for it, and do not round your answers. Be sure to include the correct units in your answers.

Answer 1

`\begin{gathered} \text{Circumference}=37.68\text{ m} \\ \text{Area}=113.04m^2 \end{gathered}`

Step-by-step explanation

the circumference(c) of a circle is given by:

`\begin{gathered} C=2\pi\text{ radius} \\ C=2\pi\text{ r} \end{gathered}`

and the area is given by:

`A=\pi r^2`

so

Step 1

find the circumference

let

radius=6

pi=3.14

replace and calculate

`\begin{gathered} C=2\pi\text{ r} \\ C=2\cdot3.14\cdot(6\text{ m)} \\ C=37.68\text{ m} \end{gathered}`

Step 2

find the Area

let

`\begin{gathered} radius=6m \\ \pi=\text{ 3.14} \end{gathered}`

replace and calculate

`\begin{gathered} A=\pi r^2 \\ A=3.14\cdot(6m)^2 \\ A=3.14\cdot36m^2 \\ A=113.04m^2 \end{gathered}`
