Answer:

Explanation:

The figure drawn is a circle. It's center is a (-5,4) just the opposite of what is in the brackets. I'm giving you this information just to be complete.

For a circle the radius is found using the lone number on the other side of the equal side -- in this case 121

The radius is the square root of that lone number.

radius^2 = 121

sqrt(radius^2) = sqrt(121)

radius = 11
