Question

Number 5: find the missing dimension of the solid. Round your answer to the nearest tenth.

Answer 1

Well, to calculate the area of a cylinder, you use
`\pi r^(2) * length`.

You now do 8 / 2 to find diameter, 4cm,
So
`\pi * 4^(2)` = 50.3

Now do 201 / 50.3 = 4,
And so the length is 4cm,

Hope this helps.
