Please help fast What are the center and radius of the circle defined by the equation x2 + y2 - 6x+By+21=0 ?

Option A

Step-by-step explanation:

The first thing we want to do here is to rewrite the equation given to us, in standard circle equation -

The " standard form " of a circle is given to be in the following form,where r = radius, centered at ( a, b )

Now as you can see, the center ( given by ( a, b ) ) should be ( 3, - 4 ). Respectively the radius is 2, and therefore the circle properties are -

Center ; radius

Hope that helps!

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
