Answer:
r = 2. The center is at (0, 3).
Step-by-step explanation:
Compare the given x ^ 2 + (y - 3) ^ 2 = 4 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 0, k = 3 and r = 2. The center is at (0, 3).
Answer:
When x=1, y=4 (1,4)
Step-by-step explanation:
Answer:
b) EF = GF , as both of them are at equal distance from the center
Step-by-step explanation:
Here we are given a ΔEFG inscribed in a circle. We have to determine whether EF = Gf and why ?
Here we see that the center is A
And EF and GF forms the chords of this circle.
The distance of these chords from the center is given as AD and DH . It is also given that both are equal.
The property of a circle says that
When chords are drawn at equal distance from the center , the chords are equal to each other. Hence we have EF and GF equal to each other.
