Answer:
9 inches
Step-by-step explanation:
The volume of a pyramid is given as:
where l = length of base of pyramid
w = width of base of pyramid
h = height of pyramid
The volume of the cylinder is already known ( ) and the other two dimensions are known as 5 in and 7 in.
From the formula of the volume of the pyramid, the height of the pyramid is given as:
Hence, the height of the pyramid is:
The pyramid's height is 9 inches.
Answer:
Because order matters when performing subtraction or division.
Step-by-step explanation:
Consider the provided information.
We need to determine why there no commutative property for subtraction or division.
Commutative property states that although the numbers in an expression are interchanged, there is no change in result.
Let us understand with the help of an example
For addition: The commutative rule is a + b = b + a.
An example in numbers would be 5 + 2 = 2 + 5
Both give 7 as result.
For Subtraction: 4 – 2 = 2, but 2 – 4 = –2
So, in the case of subtraction, moving the numbers around produces a different answer.
For division: 4 ÷ 2 = 2, 2 ÷ 4 =
So, in the case of division, moving the numbers around produces a different answer.
Hence, order matters when performing subtraction or division.
