option 3
Step-by-step explanation:
Larger the value of '' a '' makes the parabola narrow.
A positive value of '' a '' which is close to 0 makes the parabola wide.

option 3
option 4
Positive and negative value of ' a ' decides the direction the parabola opens.
But we have to find the widest parabola irrespective of the direction.
So we will find the smallest ' a '
Given:
Area of a sector = 64 m²
The central angle is .
To find:
The radius or the value of r.
Solution:
Area of a sector is:
Where, r is the radius of the circle and is the central angle of the sector in radian.
Putting , we get
Taking square root on both sides, we get
Therefore, the value of r is m.
