The line y=x+1 intersects the circlex2+y2-4x-2y+10, at points A and B. If C is the centre of the circle, find the: Centre and radius of the circle; Co-ordinates of A and B. The end points of a diameter of a circle are (6, 2) and(4,-3). Find the equation of the circle.

Step-by-step explanation:

The current equation of the circle is:

⇒

In order to get it into the standard form;

⇒

We must complete the square;

⇒

Now, collect like terms and rearrange;

⇒

We now know that the Centre is at the point (2, 1).

We can use the distance formula to find the radius;

⇒

⇒

⇒

Therefore the radius squared is 17.

Now substitute into our equation:

⇒

168

step-by-step explanation:

i am pretty sure that the answer is 168

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
