You have 60 nickles, 48 dimes, and 42 quarters. you want to divide the coins into identical groups with no coins left over. what is thye greatest number of groups that you can make?

The greatest common divisor of the three numbers is

This means that we can divide all numbers by 6:

So, if each group has 10 nickles, 8 dimes and 7 quarters, you will form 6 groups.

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 !
