A spherical glass vessel has a cylindrical neck long, in diameter; the diameter of the spherical part is . By measuring the amount of water it holds, a child finds its volume to be . Check whether she is correct, taking the above as the inside measurements, and .
For the cylinder part, Height and Radius
For the spherical part, Radius
We have to verify whether the measurements taken by the child are accurate
Amount of water it can hold Total Volume of this vessel
Volume of cylinder Volume of a sphere
Volume measured by child , which is not right
Hence, the Correct volume
