Answer:
2x+7y
Step-by-step explanation:
I'm sorry that's prolly not right but I need points that's the best I could do
SA of a sphere is 4πr² Using a sample of radius 3 the SA would be 36π²
(4πx3²) If we double the radius and make it 6, the SA would be 144π²
So for Surface area, your classmate is correct.
What about the volume? V of a Sphere = 4/3 π r³
Again using 3 the Volume of a Sphere with radius 3 = 4/3 π 27
But the volume of a sphere with radius 6 = 4/3 π 216 which is eight times the volume of the smaller sphere. (27 x 8 =216) So your friend is right about Surface Area but wrong about the volume.
