Is there anymore to the question? I need some more information to be able to help
The question is incorrect because of the apparent contradiction the question makes.
First statement says that a quantity S is equal to quantity r.
The second statement says that S = 174r.
Moreover, the quantity C is not correctly linked with the equation. Please either correct the question or explain the ambiguity.

Step-by-step explanation:
![Area =\pi r^{2} -\frac{1}{3}\pi r^{2} +\frac{1}{2}r^{2}sin\alpha \\\\\\ = \frac{2}{3}\pi 12^{2} +\frac{1}{2}12^{2}sin120 =363.9ft^{2}](https://tex.z-dn.net/?f=Area%20%3D%5Cpi%20r%5E%7B2%7D%20-%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7D%20%20%2B%5Cfrac%7B1%7D%7B2%7Dr%5E%7B2%7Dsin%5Calpha%20%5C%5C%5C%5C%5C%5C%20%20%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%2012%5E%7B2%7D%20%2B%5Cfrac%7B1%7D%7B2%7D12%5E%7B2%7Dsin120%20%3D363.9ft%5E%7B2%7D)
We are given with two dimaters of piston 8 cm and 40 cm while the load is equivalent to 15000N. We are asked to determine the force applied to the small piston. Pressure is equal to force per unit area. In a, 15,000 N / 40^2 cm2 = F2 / 8^2cm2; F2 is equal to 600 N. In b, pressure is equal to 9.375 Pa
