Question : The curved surface area of a solid cylinder of height 15 cm is 660 cm2. What is the volume (in cm3) of the cylinder? $\left(\right.$ Take $\left.\pi=\frac{22}{7}\right)$
Option 1: 2060
Option 2: 2540
Option 3: 2310
Option 4: 3210
Correct Answer: 2310
Solution : Let the radius of the cylinder be $r$. Given, the height of the cylinder, $h$ = 15 cm Curved surface area = $2\pi rh = 660\ \text{cm}^2$ $⇒r = \frac{660\times 7}{22 \times h\times 2}$ $⇒r = \frac{4620}{44 \times 15}$ $\therefore r = 7\ \text{cm}$ Now,

Question : The value of $(\sin^445°+ \cos^460°) + (\tan^445°+ \cot^445°)$ is:
Option 1: $\frac{37}{16}$
Option 2: $\frac{33}{16}$
Option 3: $\frac{35}{16}$
Option 4: $\frac{39}{16}$
Correct Answer: $\frac{37}{16}$
Solution : Given: $(\sin^445°+ \cos^460°) + (\tan^445°+ \cot^445°)$ = $(\frac{1}{\sqrt2})^4 + (\frac{1}{2})^4 + (1)^4 + (1)^4$ = $\frac{1}{4} + \frac{1}{16} + 1 + 1$ = $\frac{4+1+16+16}{16}$ = $\frac{37}{16}$ Hence, the correct answer is $\frac{37}{16}$.
