Answer:
B. 8.7 in.3
Step-by-step explanation:
The first one would reduce the size because it would now be 4/5 of the actual size
The scale factor 7/2 would enlarge it because it is getting 3 1/2 time larger than the oringanl size
V = π r^2 (h/3)
(Volume equals pi r squared, h over 3)
Diameter is 4, so the radius is half of that = 2
Plug in the numbers
V = π (2^2) (16/3)
V = π (4) (5.333)
V = 3.14 x 4 = 12.566
V = 12.566 x 5.333
V = 67.014
