A roly-poly toy in the form of a cone surmounted on a hemisphere is filled with pebbles. The base radius of the cone is 2.1 \(cm\), and the height of the conical part is \(7.5\) \(cm\). If each pebble inside the toy occupies 0.7 \(cm^3\) space, find the number of pebbles inside the toy. [Note: Take \(\pi = \frac{22}{7}\)]
Answer:
Volume of the toy \(=\) __________ \(cm^3\).
