Question

How do you write the standard form of the equation of the circle with center (0,1), r=10?

Answer 1

`x^2 + (y-1)^2 = 100`

Explanation:

the standard form of the equation of a circle is

`(x-a)^2 + (y-b)^2 = r^2`

where (a , b ) are the coords of centre and r , the radius

in this question (a , b ) = (0 ,1 ) and r = 10

hence `(x-0)^2 + (y - 1 )^2 = 10^2`
