2 answers:
Answer: 63pi cm³
Step-by-step explanation: To find the volume of a cylinder, start with the formula for the volume of a cylinder.
In this problem, our cylinder has a radius of 3 cm and a height of 7 cm so we can plug this information into our formula.
Let's start by simplifying the exponents. Remember that 3 cm² is equal to 3cm multiplied by 3 cm or 9 cm².

I always start by moving the last term to the other side
To complete the square you take term 'b' , divide it by 2 then square it
We have to add 25 to what we have and what you do to one side you have to do to the other
Now we factor what is on the left side of the equation
The last step is to move our right side of the equation back over
