You cannot have infinite solutions.
So what you need to do is find the volume and divide it by 2.
It is---------- linear--------------
Answer:
On the right is a circle with centre (0, 0), radius r and (x, y) any point on the circle. Distance between (0,0) and (x, y) equals the radius, r. If the centre is (0, 0), the equation of the circle will be of the form x2 + y2 = r2.
Yes they are correct good job
