Again if the cans height was 10cm what would the can's diameter have to be?

Question

other information: aluminium can contains 330 ml of cola.

Answer 1

volume of a cylinder (can):
V = pi * radius^2 * height

You have the height; 10 cm.

You have the volume 330 ml, but it must be converted from milliliters to cubic centimeters. That conversion can be looked up (or memorized 'cause it it easy): 1 ml = 1 cc

330 = pi * r^2 * 10

Solve for r, then multiply it by 2 to get the diameter (in cm).
