Answer:
75cm
Step-by-step explanation:
a square is all 4 sides are equal to each other, so 300 divided by the 4 sides since they are all equal is 75. double check by multiplying 4 by 75 or dividing 400 by 75.

What we do in Evaluation in math?
The verb "evaluate" is used in mathematics to mean to discover or determine the worth of something. Finding the precise value of an algebraic expression or numerical computation is relevant here as well as financial mathematics.
In mathematics, the terms "evaluate" and "solve" are often used interchangeably. Consider the following basic multiplication problem: "Evaluate the cost of six tomatoes when the tomatoes are purchased at $2 each." The student would multiply 6 by 2 to get the result of $12. The term evaluate might also come before a list of inquiries, as a list of straightforward algebraic equations.

Answer:
![328,268 mm^3](https://tex.z-dn.net/?f=328%2C268%20mm%5E3)
Step-by-step explanation:
The can in this problem has a cylindrical shape. The volume of a cylinder can be calculated with the following formula:
![V=\pi r^2 h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%20h)
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem we have:
h = 96 mm is the height of the can
d = 66 mm is the diameter of the can
So the radius of its base is
![r=\frac{d}{2}=\frac{66}{2}=33 mm](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7B2%7D%3D%5Cfrac%7B66%7D%7B2%7D%3D33%20mm)
And therefore, the volume of the can is:
![V=\pi (33)^2 (96)=328,268 mm^3](https://tex.z-dn.net/?f=V%3D%5Cpi%20%2833%29%5E2%20%2896%29%3D328%2C268%20mm%5E3)
For this case we must simplify the following expression:
![\frac {1} {2} -3 (\frac {1} {2} +1) ^ 2](https://tex.z-dn.net/?f=%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B1%7D%20%7B2%7D%20%2B1%29%20%5E%202)
Then we have to start by solving the operation within the parenthesis:
![\frac {1} {2} -3 (\frac {1 + 2 * 1} {2}) ^ 2 =\\\frac {1} {2} -3 (\frac {3} {2}) ^ 2 =\\\frac {1} {2} -3 (\frac {3} {2} * \frac {3} {2}) =\\\frac {1} {2} -3 (\frac {9} {4}) =\\\frac {1} {2} - \frac {27} {4} =\\\frac {4 * 1-2 * 27} {4 * 2} =\\\frac {4-54} {8} =\\\frac {-50} {8} =\\- \frac {25} {4}](https://tex.z-dn.net/?f=%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B1%20%2B%202%20%2A%201%7D%20%7B2%7D%29%20%5E%202%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B3%7D%20%7B2%7D%29%20%5E%202%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B3%7D%20%7B2%7D%20%2A%20%5Cfrac%20%7B3%7D%20%7B2%7D%29%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-3%20%28%5Cfrac%20%7B9%7D%20%7B4%7D%29%20%3D%5C%5C%5Cfrac%20%7B1%7D%20%7B2%7D%20-%20%5Cfrac%20%7B27%7D%20%7B4%7D%20%3D%5C%5C%5Cfrac%20%7B4%20%2A%201-2%20%2A%2027%7D%20%7B4%20%2A%202%7D%20%3D%5C%5C%5Cfrac%20%7B4-54%7D%20%7B8%7D%20%3D%5C%5C%5Cfrac%20%7B-50%7D%20%7B8%7D%20%3D%5C%5C-%20%5Cfrac%20%7B25%7D%20%7B4%7D)
