BR bisects the angle ABC, and is called the bisector of angle ABC.
Step-by-step explanation:
Step 1: Draw an arc with B as the centre to cut the arms, BA and BC, of the angle at P and Q respectively.
Step 2: Using the same radius, draw an arc centred at P.
Step 3: With centre Q and using the same radius, draw an arc to cut the arc in Step 2 at R.
Step 4: Join, B, the vertex of the angle to the point R.

Answer:
The volume of the solid is 
Step-by-step explanation:
1. Cylinder
For find the volume of a cylinder we use the next formula:

Then the volume of the cylinder is equal to 
2. Cones
For find the volume of a cone we use the next formula:

However there are two cones so we have to multiply the volume of one cone for two and we get the total volume for the cones which is 
3. Sum of the volumes
Finally we sum the volumes of the cylinder and the cones for get the final result

So approximating the result is
