1.  A semi-circular sheet of metal of diameter 28cm is bentto form an open conical cup. Find the capacity of the cup.
  2. A cloth having an area of 165m2 is shaped into the form of a conical tent of radius 5cm.       (i) How many students can sit in the tent if a student on an average occupies 5/7m2 on the ground.                                                                                                                                                       (ii) Find the volume of the cone.
  3. The surface area of a sphere of radius 5cm is five times the curved surface area of a cone of radius 4cm. find the height and volume of the cone.

Hi!
If the question (2) will be corrected as
 
A cloth having an area of 165 m2 is shaped into the form of a conical tent of radius 5 cm m.
(i) How many students can sit in the tent if a student on an average occupies 5/7m2 on the ground?  
(ii) Find the volume of the cone.
 
Then the answers to the questions are

 
 
 
Hope! This will help you.
