At what time is the cake done

Here we know that at 3:17 pm you started to bake the cake. The total revolution the minute hand on the clock makes is:

We know that:

Solving for x:

So it takes 70 minutes after you put the cake in the oven. But:

Adding this to the initial time:

Finally, the cake is done at 4:27 pm, option C.

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 !
