Help me it seems super easy tho.

The center is (9,4) and the radius is 6

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

(x-9)^2 + (y-4)^2 = 36

(x-9)^2 + (y-4)^2 = 6^2

The center is (9,4) and the radius is 6

ok

step-by-step explanation:

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
