Answer:
It is the number of flowers
Center at (-1, 3), radius = 4
A. (x+3)2+(y−1)2=4
B. (x−3)2+(y+1)2=4
C. (x−1)2+(y+3)2=16
D. (x+1)2+(y−3)2=16
Answer:
D.
Step-by-step explanation:
We are asked to write equation of a circle whose center is at point and whose radius is 4 units.
We know that equation of a circle is standard form is in format , where is the center of circle.
Upon substituting , and in the standard form of circle, we will get:
Therefore, our required equation would be and option D is the correct choice.
Answer:
It is D. (x + 1)^2 + (y - 3)^2 = 16.
Step-by-step explanation:
The general equation of a circle is
(x - h)^2 + (y - k)^2 = r^2 where the center is (h, k) and the radius is r.
So substituting the given values the required equation is:
(x + 1)^2 + (y - 3)^2 = 4^2.
