Hi there,
1 litre = 1000cm^3 = 1000000mm^3
Volume = pi x r^2 x h
1000000 = pi x 49^2 x h
h = 1000000/(49^2 x pi)
height = 132.6 mm
Hope this helps:-)

Easier to first do using centimeters, and then convert.
Internal radius is 4.9 cm.

h%2Api%2Ar%5E2=v

h%2Api%2A%284.9%29%5E2=1000
h=1000%2F%28pi%2A4.9%5E2%29, centimeters.

You then want h%2A%2810%2F1%29%28mm%2Fcm%29.
