The can is 12 cm high and the diameter Is 8 cm using the frmula V=TTr2h

Your spelled formula wrong

Given the volume of a cylinder V = pi (r2) h we simply plug in the numbers

The radius is half the diameter so r = 4cm

the height h is given as 12 cm

V = 3 (42) (12) = 3 (16) (12) = 576 cm3

Note: Generally we would use 3.14 as the rounded value of p
