Want this question answered?
x2 + y2 = 2
x2 + y2 = r2, where r is the radius.
It is x2 + y2 = 4
(x-0)² + (y-0)² = r²
If that means = 36 then then the radius of the circle is 6 units
x2 + y2 = 2
The equation of circle is (x−h)^2+(y−k)^2 = r^2, where h,k is the center of circle and r is the radius of circle. so, according to question center is origin and radius is 10, therefore, equation of circle is x^2 + y^2 = 100
x2 + y2 = r2, where r is the radius.
It is x2 + y2 = 4
(x-0)² + (y-0)² = r²
radius
The radius
If that means = 36 then then the radius of the circle is 6 units
This segment would be the radius of a circle.
x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
radius
Without an equality sign it can't be considered to be an equation but in general the equation of a circle whose centre is at (a, b) and radius is r is:- (x-a)^2+(y-b)^2 = r^2
