Answer: 4in

Step-by-step explanation:

Radius is 1/2 of diameter

Therefore you can multiple radius by 2 to get diameter

2x2 is 4

Answer:

d = 4 in

Step-by-step explanation:

Diameter is just the radius multiplied by 2. So since we know the radius is 2, just take double of that.

d = 2(2) = 4

The equation of a circle in general form is x2+y2+20x+12y+15=0 .

Harlamova29_29 [7]

Answer:

$(x +10)^2 + (y+6)^2 = 121$

Step-by-step explanation:

Given equation :

$x^2 + y^2 + 20x +12y + 15 = 0$

Standard equation of circle :

$(x - a)^2 + (y-b)^2 = r^2$

We will consider the x terms in the equation first to find a.

$(x-a)^2 = x^2 - 2ax + a^2$

-2ax = 20x

a = -20x/2x = -10

a = -10

Next consider the y terms to find b.

$(y - b)^2 = y^2 -2by + b^2$

-2by = 12y

b = -12y /2y = -6

b = -6

$(x+10)^2 + (y-6)^2 = x^2 +20x +100 + y^2 +12y + 36$

$=x^2 + y^2 + 20x +12y + 136\\$

But the given equation constant is 15. So find the difference between 136 and 15 to find the radius : 136 - 15 = 121

Therefore, radius = √121 = 11

Equation in standard form :

$(x +10)^2 + (y+6)^2 = 121$
