Correct Answer: $\frac{11}{36}$


Solution : Given: $\sin\phi=\frac{5}{6}$.
Now, $\cot\phi \cdot \sin\phi \cdot \cos\phi$
= $\frac{\cos\phi}{\sin\phi}×\sin\phi×\cos\phi$
= $\cos^2\phi$
= $1–\sin^2\phi$
= $1–(\frac{5}{6})^2$
= $1–\frac{25}{36}$
= $\frac{11}{36}$
Hence, the correct answer is $\frac{11}{36}$.
