Answer : The substances half life in days is, 5.6 days.
Step-by-step explanation :
Half life : It is defined as the amount of time taken by a radioactive material to decay to half of its original value.
All radioactive decays follow first order kinetics.
The relation between the half-life and rate constant is:

where,
k = rate constant = 0.1235 per days
= half-life
Now put all the given values in the above formula, we get:


Thus, the substances half life in days is, 5.6 days.

For this case we have that by definition, the volume of a cylinder is given by:

Where:
A: It's the radio
h: It's the height
We have according to the data:

Substituting:

Thus, the volume of the paint can is 753.6 cubic inches.
