hi please help!

2. How do you cut a 14" pizza into three pieces of equal area using only two parallel cuts? To make things simpler, consider only the first quadrant. Notice the pizza between x = 0 and x = c must be half the area of the pizza between x = c and x = 7. Use integration by trig substitution. The identity sin 202 sin cos 0 may be useful. Once an equation involving c, but without integrals, is obtained use a calculator or computer to solve for c. Round to 3 decimal places.
