The diameter of a wheel is 63 cm. What is the distance covered by the wheel by making 100 revolutions?
[Use π= \( \frac{22}{7} \) ]
If the median and the mode of a set of data are 12 and 15, respectively, then find the value of thrice the mean of the data set.
\( \frac{63}{2} \)
\( \frac{33}{2} \)
\( \frac{35}{2} \)
\( \frac{23}{2} \)
