Answer 1

The area of a circle is given by the following formula:

`A=\pi\cdot r^2`

Where A is the area and r is the radius.

Use the given value of the radius in the equation above and find the area of the circle:

`\begin{gathered} A=\pi(2)^2 \\ A=4\pi \end{gathered}`

The area of the circle is 4π
