Consider the circle $x^2+y^2=64$x2+y2=64.
State the coordinates of the centre of the circle.
What is the radius of the circle?
Find the $x$x values of the $x$x-intercepts. Write all solutions on the same line separated by a comma.
Find the $y$y values of the $y$y-intercepts. Write all solutions on the same line separated by a comma.
Graph the circle.
A circle has its centre at the origin and a radius of $4$4 units.
A circle has its centre at the origin and a radius of $\sqrt{3}$√3 units.
Write the equation for a circle with centre $\left(0,0\right)$(0,0) and radius $3$3 in the form $\left(x-h\right)^2+\left(y-k\right)^2=r^2$(x−h)2+(y−k)2=r2.
