Question

A cylindrical barrel has a radius of 7.6 ft and a height of 10.8 ft. Tripling which dimension(s) will triple the volume of the barrel?

Answer 1

do you know the formula fro the volume of a cylinder?

Answer 2

no it dosent

Answer 3

pi*r^2*h

Answer 4

if you use Angler's formula and triple the radius (put in 3r) instead of r you get
pi*(3r)^2 * h
(3r)^2 means 3r*3r= 9*r^2 or 9r^2 and you get
9 pi r^2 h
which is 9 times bigger than the original pi r^2 h

Answer 5

try the same thing using 3h instead of h

Answer 6

geeze u guys are smarter than me thanks !
