A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answers
Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

Describe Algebraic Expression?An algebraic expression is a mathematical phrase that consists of variables, constants, and arithmetic operations (such as addition, subtraction, multiplication, and division), as well as exponentiation and roots. These expressions are used to represent mathematical relationships and formulas in a concise and standardized way.
Based on the description of the diagram, we can simplify the expression as follows:
There are 4 squares labeled 1, so their total value is 4.
There are 2 rectangles labeled c, so their total value is 2c.
There are 2 squares labeled 1, so their total value is 2.
There is 1 rectangle labeled c, so its value is c.
Therefore, the expression represented by the diagram simplifies to:
4 + 2c + 2 + c
6 + 3c
So the simplified expression is:
6 + 3c.
