1. what is the solution to the system?
2. which method would be most efficient to solve the system?
it will be 31,500
this is because 2% of 45,000 is 900 and 900 x 15 = 13,500 and 45,000 - 13,500 = 31,500
the volume (v) of a cylinder is
v = area of base × height
here area of base = 64π and height = 10, hence
v = 64π × 10 = 640π in³ ← exact value
2. which method...
