How can I work out the volume of this test tube?
A test tube has a hemispherical base and straight parallel sides. If the glass it is made from is of negligible thickness how much liquid could it hold?
The test tube has a height of 12cm and a diameter of 2cm.
volume of hemisphere is 2.09 as the formula is (2/3)πr³
volume of a cylinder is V = πr2h so the volume is 34.57
add the two together and you get 36.66 (working to 2dp)
