Your answer is option H.

First find the equation of the circle.

The formula of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center. So we plug in the given information. Diameter is 10, so radius is 5.

Your equation becomes:

(x + 2)² + (y + 2)² = 25

Now you plug in the ordered pairs. It can' be option F because that's the center. Next one I plugged in was option H, (- 6, - 5).

(- 6 + 2)² + (- 5 + 2)² = 25
( - 4)² + (- 3)² = 25
16 + 9 = 25
25 = 25

Because plugging in (- 6, - 5) gives you a true statement, it lies on Circle O.

Please solve thanks lovee

Bumek [7]

Answer:

m∠1 = 93.5°

Step-by-step explanation:

By theorem of intersecting chords inside a circle,

If two chords intersect inside a circle, angle formed between the chords measure half the sum of the measures of the intercepted arcs.

m∠1 = $\frac{1}{2}(92+95)$

= $\frac{187}{2}$

= 93.5°

Therefore, measure of angle 1 is 93.5°.

If anyone knows please help me

pishuonlain [190]

Answer:

Step-by-step explanation:

Standard form of a circle is given by,

(x - a)² + (y - b)² = r²

Here, (a, b) is the center and 'r' is the radius of the circle.

For a circle having center (8, -4) and radius r = 1

Equation of the circle will be,

(x - 8)² + (y + 4)² = 1²

(x - 8)² + (y + 4)² = 1

Option (1) is the answer.

Question (2)

Circle with the center (-1, 0) and a point (2, -4) on it,

Radius of the circle = Distance between the center and the given point on circumference

= $\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

= $\sqrt{(-1-2)^2+(0+4)^2}$

= $\sqrt{9+16}$

= 5

Therefore, equation of the circle will be,

(x + 1)² + (y - 0)² = 5²

(x + 1)² + y² = 25
