C. 3 7/10

This is your answer ^^

Equation of circle is:

(x+4)²+(y-9)²=25

Step-by-step explanation:

the equation of a circle with center (h,k) and radius r is given by:

(x-h)²+(y-k)²=r²

Here, we are given (h,k)=(-4,9)

and diameter=10 units

⇒ radius=r=5 units

So, equation of circle will be:

(x+4)²+(y-9)²=5²

i.e. (x+4)²+(y-9)²=25

Hence, equation of circle is:

(x+4)²+(y-9)²=25
