A) Both A and R are individually true and R is the correct explanation of A.
B) Both A and R are individually true but R is not the correct explanation of A.
C) A is true but R is false
D) A is false but R is true.
Correct Answer: A
Solution :
Reason (R) is true [Standard Result] For Assertion \[=\frac{4}{3}\pi {{r}^{3}}.\] \[r=\frac{2}{3}\pi {{r}^{3}}\] Required area \[=2\pi {{r}^{2}}\] \[=3\pi {{r}^{2}}\] \[\frac{4}{3}\pi \times {{6}^{3}}=\pi {{(0.2)}^{2}}\times h\] Assertion (A) is true. Since, (R) gives (A) \[\frac{4}{3}\times {{6}^{3}}={{(0.2)}^{2}}\times h\] (1) holds.You need to login to perform this action.
