(a) The calculation of the volume under a complex roof requires the area of the following definite integral to be evaluated: Area = (2++3V) dx The dimensions of length are in metres. f (v) = - 6v +245 %3D (b) The fuel used by a car is defined by 80 where v is the travelling speed in km/h. What is the most economical speed of the car? In other words, determine the speed of the car which uses the least amount of fuel.
