7th Grade Math Volume Quiz
Volume is essentially the amount of space occupied by a substance or object; therefore, a way of showing the size of the object. Objects come in different shapes, and therefore their volume is also calculated differently based on their shape.

Is it true that the formula for pi =3.14
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the formula for pi is approximately equal to 3.14. Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. While the exact value of pi is an irrational number and cannot be expressed as a finite decimal, it is commonly approximated as 3.14 for practical calculations.Rate this question:

Bob jr. has can that is the shape of a cylinder and wants to fill it with water so he wants to know the volume of the can the height of the can is 5 in. and the diameter is 9in .what is the volume of the can ?
- A.
3.17.925 inches
- B.
3.17.925 inches squared
- C.
3.17.925inches cubed
- D.
3.17.926 inches cubed
Correct Answer
C. 3.17.925inches cubedExplanation
The correct answer is 3.17.925 inches cubed. The volume of a cylinder is calculated by multiplying the area of the base (which is π times the radius squared) by the height of the cylinder. In this case, the diameter of the can is given as 9 inches, so the radius is 9/2 = 4.5 inches. Therefore, the area of the base is π * (4.5^2) = 3.14 * 20.25 = 63.585 square inches. Multiplying this by the height of 5 inches gives us a volume of 317.925 cubic inches.Rate this question:

Correct Answer
A. 62.8 cm cubedExplanation
The correct answer is 62.8 cm cubed because the question is asking for the volume, which is a three-dimensional measurement. The unit "cm cubed" represents a volume measurement, while "cm squared" represents an area measurement. Therefore, the answer 62.8 cm cubed is the appropriate choice for the volume of the given object.Rate this question:
