Richarsonium has a half-life of 32 days. How many days would it take to decay from 28 grams to 12 grams? (round to 4 decimal places)

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
