It is A because it is asking for which is NOT green or red and the majority is not green or red and is DEFINITELY not B.
Answer:
4x3+2x2+6x+3 is the prime polynomial
Let the original volume be pi *r^2* h where r = radius and h = height.
The new volume will be pi *(2/5 r)^2 * 4h = pi*4/25 r^2 4h
pi*4/25r^2 * 4h / pi r^2 h = 4/25 * 4 = 16/25
The volume has been reduced by factor of 16/25.
