11 = sqrt of 121. it is a circle centred on the origin think what would happen on the line x=0 (The y axis) the equation simplifies to y2 = 121 or y =11
you can also think of eqn of a circle as x2+y2=r2

The radius of a circle inscribed in a regular hexagon equals the length of one side of the hexagon.
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
The answer depends on what they are segments of: the answer will be different depending on whether they are line segments or segments of a circle or even different circles.
Radius = 1111
The ' 1 ' in that equation is the radius.
sqrt 36 ie 6
10. Equation of circle is x2 + y2 = r2. Consider: when x = 0 y2 must = 100 so y = 10 which describes a circle centre the origin, radius 10. Similarly when x = 10 y must be 0.
chords inside circles can be any length from the diameter to almost zero length.
10 Both the x-intercept (y=0) and the y-intercept (x=0) have a length of 10 units.
The length of the arc of ABC is 22pi. You can get this answer by completing this equation 330/360*24pi, which will give you 22pi.

Circle A has more area than B
The center of a circle is the same for all circles but the length of the radius can change
x2 + y2 = 49
