How do you figure out math problems

Sedbober [7]

That is sort of a vague question, but in general you can:

1. Analyze the problem to identify:
a) What type of problem it is (word problem, algebra,etc.)
b) What the question is asking you (you must understand the question to do it)

2. Draw visuals (ex. venn diagram), graphs and tables to help you start the question

3. Create a plan to solve the question. For example the formulas and materials you need.

4. Try to solve the problem. This can be achieved in many ways.

5. If you are having problems, refer to the internet or ask a friend, teacher, parent or tutor.

A cylindrical container is used to hold drinking water on the sidelines for a football team. The maximum capacity of the contain

wlad13 [49]

To solve this we are going to use the formula for the volume of a cylinder: $V= \pi r^2h$
where
$V$ is the volume of the cylinder in cube centimeters
$r$ is the radius of the cylinder in centimeters
$h$ is the height of the cylinder in centimeters

We know for the problem that volume of our cylinder is 26,460 mL. Since 1 mL = $1cm^3$ , the volume of our cylinder is $26460cm^3$ . We also know for our problem that the height of our cylinder is 60 cm, so $h=60$ . Lets replace those values in our formula and solve for $r$ :
$V= \pi r^2h$
$26460= \pi r^2(60)$
$26460=60 \pi r^2$
$r^2= \frac{26460}{60 \pi }$
$r^2= \frac{441}{ \pi }$
$r= \sqrt{ \frac{441}{ \pi } }$
$r= \frac{21}{ \sqrt{ \pi } }$
$r=11.8$

We can conclude that the radius of the football team's <span>cylindrical container is 11.8 cm</span>
