A and B can separately do a piece of work in 24 days and 16 days respectively. They worked together for 6 days, after which B was replaced by C. If the work was finished in next 3 days, then the number of days in which C alone could do the work will be?

C can complete the work in 12 days.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
