x2 +y2 = R2 =16 = radius 2 R = 4
That's the equation of a circle with its center at the origin and a radius of 8.
X2 + y2 = 100 = r2 r = 10
If that equals 16 then the radius is 4
x2 + y2 = 144 = radius squared radius = sqrt (144) = 12 diameter = 2 x radius = 24
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
x2 +y2 = R2 =16 = radius 2 R = 4
Centre = (0,0), radius = sqrt(5)
X2 or 2 times x?
7
Center is (0, 0) . . . the origin.Radius is 7.
4
The centre is (3,-1) and the radius is sqrt(10).
Radius = 1111
