In the diagram below, M. L and K are points on the surface of the earth. (a) [n - 3.142 and R - 3437nm). 80N M K -32'E 48W 85'S (i) Determine the difference in longitudes between points M and K. (ii) Calculate, in nautical miles, the distance between (a) M and K along latitude 80 N, ( b ) K and L along longitude 32.E. (b) The following diagram shows the frustum of a cone. The top and bottom diameters are 6cm and 18cm respectively. [Take it as 3.142] 6cm 10cm 18cm the frustum. Given that its perpendicular height is 10cm, calculate the volume of
