Answer:
A.v=п*1/4*S^3
Step-by-step explanation:
the formula for the volume of a cylinder is v=п*r^2*h. here r=d/2=S/2 so r^2=S^2/4. h is the same lenght as the side of the cube so h=s. and then you just have to substitute r and s in the formula

The activation energy is the amount of energy required to initiate a certain reaction. The activation energy may considered as an "energy barrier" that has to be overcome in order for a reaction to begin. If a reaction has a lower activation energy, then it will occur more easily and at a faster rate than a reaction with a higher activation energy. Therefore, the reason that reaction 1 is faster than reaction 2 is because it has a lower activation energy than reaction 2.
