Please help! I only have 20 more minutes! Sergio has two similar cylindrical pots, Pot A and Pot B. The radius of Pot A is 20 inches, and the radius of Pot B is 4 inches. What is the ratio of the volume of Pot A to the volume of Pot B?

ganeshie8 · Answer

For similar figures,

ratio of volumes = (ratio of lengths)^3

ganeshie8 · Answer

so simply find the ratio of radii,
then cube it

anonymous · Answer

Okay well for Pot A the formula would be: V= 3.14 x 20^2 x h. Right? Which then would give you: V = 3.14 x 400 x h?

ganeshie8 · Answer

we  don't really need to all that

ganeshie8 · Answer

`The radius of Pot A is 20 inches, and the radius of Pot B is 4 inches. `

 ratio of radii = 20/4 = 5
therefore, ratio of volumes = 5^3 = 125
