Question

find the height of a cylinder with a volume of 100 cm3 and a radius of 2 cm. π=3.14. Please show how you got the answer! Thanks!

Answer 1

The equation to find volume is V=
`\pi`r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.

I hope that helps!
