An ice cream shop sells 6 different flavors, 4 toppings, and 3 types of cones. How many different combinations of three differen
irga5000 [103]

Answer:

360

Step-by-step explanation:

To calculate the number of different combinations of 2 different flavours, 1 topping, and 1 cone, we are going to use the rule of multiplication:

             6          *        5             *           4           *          3             = 360

      1st flavour           2nd flavour  topping              cone

Because first, we have 6 possible options for the flavour, then we only have 5 possible options for the 2nd flavour. Then, we have 4 options for the topping and finally, we have 3 options for the cone.

It means that there are 360 different combinations of two different flavours, one topping, and one cone are possible

(1/3) × the cone's volume = The cylinder's volume.

Step-by-step explanation:

Step 1:

The volume of any cone is obtained by multiplying \frac{1}{3} with π, the square of the radius (r^{2}) and the height (h).

So the volume of the cone, V=\pi r^{2} \frac{h}{3}.

Step 2:  

The cylinder's volume is nearly the same as the cone but instead by multiplying \frac{1}{3} we multiply with 1.

So the cylinder's volume is determined by multiplying π with the square of the radius of the cylinder (r^{2}) and the height of the cylinder (h).

So the the cone's volume, V = \pi r^{2} h.

Step 3:

Now we equate both the volumes to each other.

The cone's volume : The cylinder's volume = \pi r^{2} \frac{h}{3}: \pi r^{2} h = \frac{1}{3} : 1.

So if we multiply the cone's volume with \frac{1}{3} we will get the cylinder's volume with the same dimensions.
