If the diameter and the height of a cylinder are 12 cm and 10.5 cm, respectively, then using π = \( \frac{22}{7} \), find the volume of the cylinder.
The value of
\(\left(-\frac{5}{3}\right)\times\left(\frac{9}{25}\right)+\left(\frac{1}{5}-2\right)\)
\( \frac{-12}{5} \)
0
\( \frac{-4}{5} \)
\( \frac{9}{5} \)
P, Q, R, S, T and U are six siblings who passed their class tenth exam in different years viz. 2001, 2003, 2005, 2007, 2010 and 2012 but not necessarily in the same order.
P passed in one of the years before S and after R. Only Q passed before R. T passed in the year immediately after S. U passed in one of the years before P. Who passed their class tenth exam in the year 2007?

According to mirror formula, the focal length of a spherical mirror is equal to:
\(\frac{uv}{u-v}\)
\(\frac{uv}{u+v}\)
\(\frac{u-v}{uv}\)
\(\frac{u+v}{uv}\)
