Using (x-h)^2+(y-h)=r^2
sub in -1 and 2 for h and k
get sqrt of 4 for r
anser is therefore
(x+1)^2+(y-2)=2^2
Have and Wonderful Day,

A 'unit cube'. Just like a circle with radius 1 and center at (0,0) is a 'unit circle'.
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
Area = Pi(radius)squared. You only need the radius of a circle to find the area. To find the radius, when you have the diameter, divide the diameter by 2, because the diameter forms two radii. After you have found the radius, plug in the radius into the area equation: Area = Pi(radius)squared In other words, you can say the other equation for the area of a circle is: Area = Pi(1/2Diameter)squared
If a circle has a radius of 1, the diameter is 2, and the circumference is 6.28 (approximately).
The radius of a circle is always 1/2 its diameter.
3.14 x 1
This makes no sence
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
A unit circle is a circle of radius 1. If it's center is at the origin of an xy-coordinate system, then the equation is x (squared) + y (squared) = 1
The equation is: (x+1)^2 +(y+5)^2 = 36
(x - 1)2 + (y + 1)2 = 1
(x + 2)2 + (y - 2)2 = 1
(x + 2)2 + (y - 2)2 = 1
It is (x - 1)^2 + (y - 1)^2 = 5^2
It is: (x+3)^2+(y-1)^2 = 25
(x + 1)2 + (y + 5)2 = 36
