Volume of the cone:
V = 1/3 r² π h
If we double the radius:
V 1 = 1/3 ( 2 r )² π h = 4 · 1/3 r² π h
V 1 = 4 V
Answer: the volume becomes 4 times larger.

Answer:
im relativley sure that you just move the "." 7 spaces to the left, in this case you would get 348,790,000
Step-by-step explanation:
No.
0.3^4 or 0.3x0.3x0.3x0.3= 0.0081
0.9^2 or 0.9x0.9=0.81
These are not equivalent.
