The equation for any circle centered at the origin with a radius r is the following:

x^2+y^2=r^2

By looking at the picture, we can see that the radius is 5. We can also use the distance formula to find the distance between (0,0) and (-3,-4), and we will also get 5.

Thus, r=5.

This makes the equation:

x^2+y^2=5^2

x^2+y^2=25

That should be your answer, let me know if this is confusing in any way.

Happy Studying~

Explain how to find the sum of 3/10 + 4/100
Neporo4naja [7]

Answer: 17/50

Step-by-step explanation:

First, to add fractions, we must find a common denominator, in this case, 100.

Then, we must make the fractions being added all have the common denominator.

So, we must multiply 3/10 * 10/10, which equals 30/100

30/100 + 4/100

Then, just add across the numerator to get 34/100, which can be simplified to 17/50
