Here's the formula for exponential decay:
(where A = new amount, p = principal (starting) amount, k = rate of decay, and t = time)
Let's use what we know and fill in the expression.
And now we solve for t.

c)
Step-by-step explanation:
A tank has the format of a cylinder.
The volume of the cylinder is given by:
In which r is the radius and h is the heigth.
The problem states that the diameter is measured to be 15.00 ft. The radius is half the diameter. So, for this tank
ft
The height of the tank is 22 ft, so .
a) Volume of the tank in :
b) Volume of the tank in :
We must convert both the radius and the height to m.
Each feet has 0.30 m, so:
Radius:
1 feet - 0.30m
7.5 feet - r m
Height
1 feet - 0.30m
22f - h m
The volume is:
c) Volume of the tank in :
Each m has 100 cm.
So
The volume is:
