Radius = 1111
The ' 1 ' in that equation is the radius.
sqrt 36 ie 6
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
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
