The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
Answer:
120
Step-by-step explanation:
So you basically want us to answer for u anyway well it’ll be:
For 2< it’ll have to be something greater that two or 2 and then for <5 it’ll be the same so for example if it was like that I’ll do it like this: 3x5=15
Hope That Helped!
