Answer:
5652 cm³
Step-by-step explanation:
V = 2πr² + 2πrh
= (2 × 3.14 × 3.14 × 20 ×20) + (2 × 3.14 × 20 × 25)
= 2512 + 3140
= 5652 cm³

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.
