Answer 1

See attached graph

Explanation:

We need to convert the polar coordinates into Cartesian coordinates using the rules
`x=r\:cos\theta` and
`y=r\:sin\theta` (see table in attached file).

The converted points will start to resemble a circle with a horizontal pole and a diameter of 4, so by connecting the points, we get our equation
`r=4\:cos\theta`.
