Write an equation of the circle with center (-4.8) and radius 9

(x+4)^2 +(y-8)^2 = 81

Step-by-step explanation:

The equation of a circle can be written as

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

where (h,k) is the center and r is the radius

(x- -4)^2 + (y-8)^2 = 9^2

(x+4)^2 + (y-8)^2 = 9^2

(x+4)^2 +(y-8)^2 = 81

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
