Question

2. Right circular cylinder AA has volume 2,700 and radius 3. Right circular cylinder BB is similar to cylinder AA and has volume 6,400. Find the radius of cylinder BB.

Answer 1

7.11

Explanation:

To solve this you just have to make a rule of thirds, so you have that a cylinder has a volume of 2,700 and radius 3, and you want to find out the radius of a similar cylinder volume 6,400:

`(3)/(2700) =(x)/(6400) \\\x=frac{3*6400}{2700}\\ x=7.11`

So we know that the radius of a cylinder with volume 6400, and that is similar to the 2,700 cylinder with radius 3, is 7.11
