B. 137.32 cm3
Step-by-step explanation:
So what we know is that
Height = 12
Diameter is 6 which would make the radius 3.
The current volume is 339.12
12cm × 1.12 = 12.44 (This is the new height.)
3cm × 1.12 = 3.36 9 (This is the new radius)
Volume of future can (V2) = πr²h = 3.14 × 3.36 ×3.36 × 13.44 = 476.43
Then you would subtract 476.43(new volume) - 339.12(old volume) = 137.31
That would round to 137.32 cm3.
So the answer is B. 137.32 cm3.
