If a cylindrical pipe made of metal is 3 cm? f the internal radius is 10 cm? Find the volume of metal used in making 3 cm of the pipe

AAAaannndd the bot gets it wrong yet again!

if the metal is 3cm thick, then
v = π(13^2-10^2)*3 = 207π cm^3

Volume of metal used in making 3 cm of the pipe = π * (10 cm)^2 * 3 cm = 300π cm^3
