Question

A company is designing a new cylindrical water

bottle. The volume of the bottle will be 120 cm3.
The height of the water bottle is 8.9 cm. What is
the radius of the water bottle?

Answer 1

2.07

Explanation:

Howdy!

I remember this from a while ago. they had us memorize a bunch of useless formulas which I still seem to remember the formula is:

`r=\sqrt{(v)/(\pi h) }`

volume divided by pi*height. then you square root all of that

3.14*8.9= 27.946

120/27.946=

4.29 the square root of 4.29 is 2.07 because the square root of 4=2 and the square root of 29=7 (.07)

so 2.07 is your answer!
