The equation represents a circle centered at (3,5) and passing through the point (-2,9) will be,
What exactly is a circle?
It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.
Given data;
The Centre of the circle is,(h,k)=(3,5)
The circle traverses (-2,9). Consequently, the radius of the circle r is equal to the separation between (3, 4) and (-2,1).
So radius;
Now equation of the circle with center (h,k) and radius r is
Hence equation represents a circle that will be,

Answer:
131
Step-by-step explanation:
Using proportion,
If Out of 550 calculators = 6 are defective,
Then out of 12000 calculators = ? are defective
= 21.8 * 6
= 130.8 ≈ 131
∴ Approximately 131 calculators are defective
