Question

Given the equation: ( x + 3)2 + ( y - 4)2 = 25

1. Center: ( , ) ??

2. Radius: ??

3. Diameter: ??

Answer 1

Answer:

See below

Step-by-step explanation:

Center:   (-3, 4)

radius = r = $\sqrt{25}$ = 5

diameter = 2r = 10

Answer 2

Answer:

Center= (3,-4)   Radius=5   Diameter=10

Step-by-step explanation:

The numbers (3,-4) are the coordinates in the center of a circle. The radius is squared to get the end number so to get the radius, you have to find its square root- $\sqrt{25$ =5. The diameter is 2 times bigger than the radius so 5 times 2= 10.
