The carpenter uses a solid spherical chunk of wood to craft hemispherical finials out of it. If the radius of the spherical chunk is \(14 \ cm\). Using the given information, analyse and answer the following. (Note: Use \(\pi = \frac{22}{7}\))
1. What is the radius of the largest hemispherical finial he can carve from the spherical chunk?
2. What is the total surface area of the largest hemispherical finial?
3. What is the curved surface area of the largest hemispherical finial?
4. How many hemispherical finials of maximum size can be crafted from the spherical chunk?
