Question

You wish to fill a cylinder-shaped glass with iced tea. How much room is left for the tea If you put 5 ice cubes in the glass? Using the figures shown, find the volume left in the glass. Use 3.14 to approximate pi. Round your answer to the nearest whole number.

Answer 1

Volume of cylinder
V = π r^2 h = 3.14 x 2^2 x 6.5 
V = 81.64 in^3

Volume of 1 cube:
V = a^3
V = 1.5^3 
V = 3.375

5 ice cubes so total volume of cubes = 3.375 x 5 = 16.875 in^3

Volume left in the glass = Volume of cylinder - total volume of cubes
Volume left in the glass = 81.64 - 16.875 
Volume left in the glass = 64.765
Volume left in the glass = 65 ...Round your answer to the nearest whole number.

Answer
65 in^3
