The volume of the water storage tank is the amount of space in it
The volume of the water storage tank is 6468 cubic feet
<h3>How to determine the volume?</h3>
The given parameters are:
Radius (r) = 21 feet
Height (h) = 14 feet
The shape of the water storage tank is a cone.
And the volume of a cone is:
V = 1/3πr^2h
So, we have:
V = 1/3 * 22/7 * 21^2 * 14
This gives
V = 6468
Hence, the volume of the water storage tank is 6468 cubic feet

Answer:
Total amount paid to staff = $250
Step-by-step explanation:
Given:
Weekly payment = $200
Commission = 5% on sales
Amount of jewelry = $1,000
Find:
Total amount paid to staff
Computation:
Total amount paid to staff = Weekly payment + Commission
Total amount paid to staff = $200 + $1,000(5%)
Total amount paid to staff = $200 + $50
Total amount paid to staff = $250
