If you doubled the radius of a sphere, how would the surface area change?
2 answers:
The area scale factor is the length scale factor squared. The length scale factor in this question is 2 (from the doubled radius) so the area scale factor is 2 squared, 4. This means that the surface area will be 4 times larger than it was originally.
Answer:
The area will get quadrupled that is four times.
Step-by-step explanation:
Surface area of sphere, A = 4πr²
If you doubled the radius of a sphere how would the surface area change.
New radius = 2r
New surface area of sphere, A' = 4π x (2r)²=16πr² = 4A
So the area will get quadrupled that is four times.

Answer:
B
Step-by-step explanation:
You can eleminate D right off the bat, no one said they would go if more were planted.
A is just wrong as half of 75 is 35 and 27 is not greater than 35.
It is between B & C but 27/75=.36 which would make B the most correct.
