The opposite of 12.1 is 12.2
A is correct:
Let volume v, length l, and h height.
v= (l²h)/3
v=(x²9)/3
v=3x²
above is the distance formula, plugging your numbers from P(x1,y1) and Q(x2,y2).

In this item, it is not given that there has to be specific arrangement or order as to how the questions are going to be answered. Hence, the concept that can be used in order to answer this item is the concept of combination which states that,
nCr = n! / (r!)(n - r)!
This is read as "combination of n taken r". In this item, n = 10 and r = 4. Substituting the known vaues to the equation,
10C4 = (10!) / (4!)(10 - 4)!
10C4 = 210
Therefore, the number of which is which the questions can be answered is 210.
