Question

Write the standard form of the equation of a circle with radius 10 and center (9,3)

Answer 1

`(x-9)^(2)+(y-3)^(2) =100`

Explanation:

The standard form formula for a circle equation is
`(x-h)^(2)+(y-k)^(2) =r^(2)`, where (h,k) represents the center of the circle, and r represents the radius.

r=10

(h,k)= (9,3)

`(x-h)^(2)+(y-k)^(2) =r^(2)`

`(x-9)^(2)+(y-3)^(2) =10^(2)\\(x-9)^(2)+(y-3)^(2) =100`
