Question

Write the standard form of the equation of the circle with radius 7 and center (5,−7).

Answer 1

Answer:

$(x-5)^2+(y+7)^2=49$

Step-by-step explanation:

Use $(x-h)^2+(y-k)^2=r^2$ for the equation of a circle in standard form with radius $r$ and center $(h,k)$. Therefore, the equation of the circle in standard form is $(x-5)^2+(y+7)^2=49$
