Data Sufficiency: In each of the following Questions you find a question followed by two statements labelled (I) and (II). You have to decide whether these statements answer the given questions. Mark your option as
Question 183
What is the volume of the right circular cone?
I) Base radius of the cone is 12 cm,
II) Semi vertical angle of the cone is $$45^\circ$$
Solution
Statement 1 alone gives us no idea what the height of the cone might be.
Only when we combine statement 1 and 2 we can see that height = base radius because semi-vertical angle = 45 degrees.
Hence, both the statements are needed.
