Question

Write the equation of a circle with a center at (0, 3) and a radius of 1. x^2 + (y + 3)^2 = 1 <-- I came up with this am I correct? @waterineyes

Answer 1

Slight mistake..

Answer 2

is it x^2 + (y-3)^2 =1

Answer 3

Equation of Circle is given by:

\[(x - h)^2 + (y - k)^2 = r^2\]

Answer 4

Yeah this one is just fine... Well Done..

Answer 5

Thank you. Now I did another one. Would you mind telling me if I am correct on this one?
Write the equation of a circle with a center at (–3, –8) and a radius of 1/3
I got (x + 3)^2 + (y + 8)^2 = 1/3

Answer 6

See on right hand side it is radius square..

So earlier it was 1 so you did 1^2 = 1.

But now it is 1/3, so what is the square of 1/3 ?? That you will write on RHS..

Answer 7

Is it 1/9?

Answer 8

In equation, on RHS, we write r^2 ie radius square, so you can't write 1/3 instead write square of it..

Answer 9

Yeah that is right...

Answer 10

Thank you! You have been an amazing help!

Answer 11

No, I just know fewer things and not at all good at math... :)

Answer 12

You are welcome dear..

Keep practicing more, Practice is other name of Math.. :P
