Answer: The answer is
Step-by-step explanation: We are to find the equation of the parabola with x-intercepts (-2,0), (1.2,0) and y-intercept (0,-4).
Therefore, axis of symmetry is
Let the equation of the parabola be
Substituting the points (x,y)=(0,-4) and (1.2,0) in the above equation, we find that
and
Solving the above two equations, we get
So, putting the values of 'a' and 'k' in the equation of the parabola, we get
Thus, the equation of the parabola is
The equation of a circle is represented as :
where,
- "h" represents x - coordinate of the center of circle
- "k" represents y - coordinate of the center of circle
- " r " represents Radius of the given circle
So, from above equation we get:
Therefore, Radius of the given circle measures 6 units.
