A spherical glass vessel has a cylindrical neck 8 cm long, 2 cm in diameter; the diameter of the spherical part is 8.5 cm. By measuring the amount of water it holds, a child finds its volume to be 345
. Check whether she is correct, taking the above as the inside measurements, and π = 3.14.
Solution:
Diameter of Sphere
cm
Radius of Sphere
cm
Volume of Sphere
Diameter of Cylinder
cm
Radius of Cylinder
cm
Height of Cylinder
cm
Volume of Cylinder
Volume of Water in the Vessel = Volume of Vessel
= Volume of Sphere + Volume of Cylinder = 321.392+25.12 = 346.512
It means, she was not correct.
