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.**
