I'm thirsty!

Geometry Level 1

Sam filled a 30 cm tall cylindrical water bottle. He was very thirsty, but before he could take a sip, his physics teacher asks him how much volume is in that bottle. The teacher wouldn't let Sam drink until his question is answered. Sam wants to know how to calculate it. Can you help?

All that he knows is that the diameter of the bottle is 80 cm.


The answer is 150796.45.
