Surface area I think is the circle. So the formula to find the area of the circle is to do Pi times radius squared. Pi= 3.14 Radius in this case will be 2.2. (Radius is how much it measures out from the middle.) then you want to do 2.2 x 2.2 (since it's square) So the answer would be equal to (I think) 15.1976
The angle in the polar form of a complex number can have any multiple of 2π radians added to it, and the number will be the same number. That is, there are an infinite number of representations of a complex number in polar form.
