Question

Radius = 8 mFind the circumference and area of the circle. Use a (not 3.14) and round your answer to the nearest hundredth (2 decimal places)Help me

Answer 1

Circumference of the Circle:

The formula for calculating the circumference of the circle is:

`C=2\pi r`

Using,

`r=8`

We can calculate the circumference to be:

`\begin{gathered} C=2*\pi*8 \\ C=16*\pi \\ C=50.26548 \end{gathered}`

To the nearest hundredth, the circumference is:

`C=50.27m`

Area of the Circle:

The formula for calculating the area of a circle is given to be:
