Q3: What is the maximum number of parallel tangents a circle can have?

Answer: 

The maximum number of parallel tangents a circle can have is 2. Parallel tangents are formed, if perpendicular lines are drawn, at the end points of a diameter. 

Q4: What is the General Equation of a circle with center (0, 0), and radius r? 

Answer: 

The general equation of a circle with center (0, 0), and radius r is, 

x² + y² = r²
