Answer:
20.5 cm
Step-by-step explanation:
I just used Pythagorean theorem in which c^2=a^2+b^2
so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm
g(x) = x^3 − x^2 − 4x + 4
g(x) = x^3 + 2x^2 − 25x − 50
g(x) = 2x^3 + 14x^2 − 2x − 14
ANSWER

EXPLANATION
Given;

The standard equation of circle of a circle centered at (h,k) with radius r is;

Re-write the given equation in the standard form, we have;

Hence, h=-3, k=-5, radius is 4
