A student intends to produce a model globe of diameter \(56 \ cm\) for a science exhibition at school. In order to buy the materials for his project, he requires the following measurements. (Note: Use \(\pi = \frac{22}{7}\))
1. Determine the radius of the globe.
2. Determine the total surface area of the globe?
3. Calculate the area of the printed map required to wrap the entire surface of the globe without gaps?
4. If the printed map overlay costs \(\text{Rs.} 2/ cm^{2}\), how much money he needs?
