The question consists of two statements, namely, Assertion (A) and Reason (R). Please select the correct answer.
Assertion (A) | Reason (R) |
The outer and inner radii of a hollow cylinder 2 m 10 cm long are 5 cm and 3 cm respectively. If it is made up of copper, then volume of copper in it is | The volume of a hollow cylinder of length |
external radius 
and internal radius 
is given by 
The volume of a hollow cylinder with external and internal radii R and r respectively and height h 
Thus, the volume is 
Both Assertion (A) and Reason (R) are true and Reason (R) is a correct explanation of Assertion (A).
