Question

HELP PLEASE!! Find the radius of the circle given by the equation (x+3) ^2 + (y-12) ^2 =64

Answer 1

8

Explanation:

1) luckily, this equation is in standard form of a circle:

(x – h)^2+ (y – k)^2 = r^2

where r=radius

to find the radius by itself remove the square by taking the square root of r

square root of 64=8

8 is the radius

hope this helps!
