I have another question. If I have 3.14 cm^2/(2.00cm/2)^2 would it be 3.14 cm?

Im not one of those experts doing this, but don't you have a calculator?

Anyways there are sites that help:
w w w. quickmath . c o m (no spaces)

Sometimes I goof on simple algebra problems and I use their equation solver to fix mistakes, etc.... use it and plug in your equation with variables (don't put in the cm, you can just add it at the end)

I don't know what the / mark in the denominator means.

To solve this question, we need to perform the calculations step by step.

First, let's simplify the expression:

3.14 cm^2 / (2.00 cm/2)^2

Inside the parentheses, we have (2.00 cm/2)^2. According to the order of operations, we need to divide first, and then square the result:

(2.00 cm / 2) = 1.00 cm

Now, let's square it:

1.00 cm^2 = 1.00 cm^2

Now we can substitute this value back into the original expression:

3.14 cm^2 / 1.00 cm^2

When dividing two quantities with the same units, the units cancel out. Therefore, the result will just have the units of the numerator:

3.14 cm^2 / 1.00 cm^2 = 3.14

So, the value is 3.14, but it does not have any units. It is just a numerical value.
