A vessel is in a conical shape. If its volume is 33.264 litres and height is 72cm, the cost of repairing its cross sectional area at Rs. 12 per sq.m is:A. 5.94B. 6.94C. 7.95D. None of these

In the figure (not to scale) AB = CD, angle DAP = angle DPA and A,B,C,D are concycli. If angle ADC = 80°, then find angle ACD.

Solve : 2^(x+2)+2^(x-1)=9
