Answer:

The equation is x² + y² = 144.

Step-by-step explanation:

This works the same way as before.

You know that at the origin, it equals (0, 0). So, we have no need to insert values for h and k. Therefore, it will just be x² + y² = r².

R is your radius, and this is given as 12 units. So, r = 12. Therefore, r² = 144.

Your final equation is x² + y² = 144.

Ex 1:
2/5 x 4/5
Multiply both the numerators together and then multiply both the denominators together. You would multiply 2x4 which is 8 and 5x5 which is 25. Which leaves you with 8/25 and it will stay that way because you cannot simplify it further.

Ex 2:
2/5 and 5/3
Multiply across 2x5/5x3 and you end up with 10/15 which can be simplified/reduced to 2/3 because they share a common factor of 5.
