2. Find the height of a cylinder with a volume of 100 cm and a radius of 2 cm.

The height of the cylinder is 25π cm.

Step-by-step explanation:

V=πr^2h             This is the formula for the volume of a cylinder.

100=π(2)^2(h)     Plug in 100 for volume and 2 for radius.

100=4π(h)           2^2 is 2×2 which is 4

100÷4π=h           Divide both sides by 4π

25π=h                 Here is your answer!

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
