Question

A conical cup 18 cm high has a circular base of diameter 14 cm. The cup is full of water, which is now poured into a cylinder vessel of circular base of diameter 10 cm. What will be the height of water in the vessel?


A-25π
B-15π
C-10π
D-20π​

Answer 1

Answer:

Radius of the conical cup r=14 by 2 =7cm and height of the cup h=18cm Therefoe

Step-by-step explanation:

volume of water in the cup=1 by 3 πr²h=1 by 3×22 by 7 ×7×7×18=924cm²

Now radius of the circular cylinder R=10/2cm=5cm

Let the height of water be H centimetres Then

Volume of water=πr²h=22/7×5×5×h=25×22/7 HCM

This volume is equal to the volume of water poured out from the cup i.e.

22/7×25h=924 or h=924×7/22×25=11.76cm

therefore height of water in the vessel=11.76cm
