1. the equation of a circle is (x + 4)2 + (y – 6)2 = 48
what is the center of the circle?

what is its radius (round to the nearest tenth)?

Center of circle = (-4,6)

Radius = 6.9

Step-by-step explanation:

Formula of a circle:

Center of circle = (a, b)

Radius= c

Your question is:

a= - 4 because - (-4) will only equal to 4

b= 6 because - (6) will only equal to - 6

If (a, b) is the center of the circle, thus (-4,6) is the center of the circle.

To find the radius.

If c = radius.

Note: Please use a calculator when finding the radius.

Thus to the nearest tenth

c= 6.9

Thus the radius is 6.9

8121 because

130,000 divided by 16 is 8121
