Answer:
The radius is 15
Step-by-step explanation:
In the equation, 225 is a square of a radius, so the radius itself is the square root of 225, which is 15.
Given equation is :
=0
Taking out
common we get,
=0
Now solving this we get,
As 11 is not factor-able, we will solve it using the formula,

a=1 b=5 and c=-11
we get,
and 
Since they have to equal each other you can do reverse math, and if I’m not wrong i think its C. x=3
When in doubt, draw a picture. The vertex of the equation is at (3,0) and the y-intercept is at (0,4.5). The answer is D
