Hi there!
The standard form of the equation of a circle is:(x-a)^{2} + (y-b)^{2} =  r^{2}

With (a, b) representing the centre and r representing the radius of the circle. Since the centre of the circle is (0, 0) and the radius is 3, we get the following equation:
(x-0)^{2} + (y-0)^{2} = 9 \\   x^{2} + y^{2} =   9

~ Hope this helps you!

How Do Solve 3/4=3/8x-3/2 And Show All Your Work
lubasha [3.4K]
It's too hard for me to show all the work, but you can find a common denominator in 8.

Change 3/4 to 6/8 and -3/2 to -12/8.

Now that all the fractions have the same denominator, you can multiply the whole problem by 8 and cancel out all denominators.

You are left with 6=3x-12

Add 12 to 6 and cancel out on the right side.

18=3x

Divide by 18 by 3

x=6
