Question

What are the center and radius of the circle with equation (−)+(−)=?Open x minus 4 close squared . Plus . Open y minus 9 close squared . Equals , 1 question mark

Answer 1

Center and radius of the circle of the equation
`{(x - 4)^(2) + (y - 9)^(2) = 1`

center = ( 4,9) Radius = 1

Explanation:

Given -

Equation of circle is
`(x - 4)^(2) + (y - 9)^(2) = 1`

The equation of circle is represented by

`\boldsymbol{\mathbf{(x - a)^(2) + (y - b)^(2) = r^(2)}}`

where a and b are center of circle and radius r

Comparing these equation

then a = 4 and b = 9 and r = 1
