Answer:
Step-by-step explanation:
Answer: a = (1/4)a
In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
I think its x=2 sorry if im wrong
x^2 = 64
√x² = √64
x = 8, -8
answer is B
1000 is the best answer yet
