Answer:
D. 9
Step-by-step explanation:
The segment lengths are equal, so ...
x^2 = 90-x
x^2 +x -90 = 0 . . . . . . add x-90 to put in standard form
(x +10)(x -9) = 0 . . . . . factor
The solutions are the values of x that make the factors zero: -10, 9.
The positive value of x is 9.
The radius of the new sphere is 9
The new SA should be 1017.36 in
New volume should be 3052.08in^3
A ratio equivalent to 3/20 can be 6/40 or even 9/60
