Question

Write the question in standard form for the following? Center (13, -13) Radius = 4

Answer 1

`(x-13)^2+(y+13)^2=16`

Explanation:

`"the equation of a circle in "color(blue)"standard form"` is.

`color(red)(bar(ul(|color(white)(2/2)color(black)((x-a)^2+(y-b)^2=r^2)color(white)(2/2)|)))`

`"where "(a,b)" are the coordinates of the centre and r"`
`"is the radius"`

`"here "(a,b)=(13,-13)" and "r=4`

`rArr(x-13)^2+(y-(-13))^2=4^2`

`rArr(x-13)^2+(y+13)^2=16larrcolor(red)" in standard form"`
