The center of the circle is (-9, 46), radius is 11.09053 and the diameter is 22.18, if the equation of circle is $(x+9)^{2} +(y-46)^{2}= 123$ .

Step-by-step explanation:

The given is,

$(x+9)^{2} +(y-46)^{2}= 123$

Step:1

Equation of circle is,

$(x-h)^{2} +(y-k)^{2}= r^{2}$ ...................(1)

Where,

(h, k) - Center of circle

r - Radius of circle

From given,

$(x+9)^{2} +(y-46)^{2}= 123$ ...............(2)

Comparing equation (1) and equation (2),

Center - (h, k) = (-9, 46)

$r^{2} = 123$

Take square root on both sides,

$r = \sqrt{123}$

= 11.09053

r ≅ 11.09053

Formula for diameter,

d =2r

Substitute the value of r,

= (2)(11.09053)

=22.18

diameter, d = 22.18

Result:

The center of the circle is (-9, 46), radius is 11.09053 and the diameter is 22.18, if the equation of circle is $(x+9)^{2} +(y-46)^{2}= 123$ .

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
