x2 + y2 = 2
It is x2 + y2 = 4
x2 + y2 = 49
(x-0)² + (y-0)² = r²
x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
x2 + y2 = 2
It is x2 + y2 = 4
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 = 49
(x-0)² + (y-0)² = r²

x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25

There are infinitely many points. One of these is (10, 0).
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
