V= πr^2h
This is the formula for volume of a cylinder. The volume formula builds off the area formula. Where area is more 2-dimensional, volume is 3-dimensional. You can think of a flat sheet of paper for area (2-dimensional) and a solid box for volume (3-dimensional).
Usually your teacher would give the formulas when starting this section of math. From there, either keep a list of needed formulas in your math folder for easy reference, or try to memorize the formulas for the current section of math you are working on. Some teachers allow formula reference sheets and some do not.
Hope this answers your question! :)

Answer:
150(10s + h)
Step-by-step explanation:
We need to write an expression for the total items they shipped.
Let each skateboard be s.
Let each helmets be h.
The factory ships 100 boxes with 15 skateboards in each box. That is:
100 * (15 * s) = 1500s
The factory ships 10 boxes with 15 helmets in each box. That is:
10 * (15 * h) = 150h
The total number of items shipped is therefore:
1500s + 150h = 150(10s + h)
This expression represents the total number of items shipped.
Answer:
12 and 36
Step-by-step explanation:
x+3x=48
4x=48
divide by 4
x=12
48-12=36
Given: 16cm long, 6cm wide, 23 cm tall
