When students are admitted to a particular university, they are given a six-digit identification number (). If the first digit must be either a 0 or 1, how many identification numbers are possible?

200,000 identification numbers are possible

Step-by-step explanation:

For the first digit, there are only two possible outcomes, 0 or 1.

For the next five digits, there are 10 possible outcomes(0,1,2,3,4,5,6,7,8,9).

How many identification numbers are possible?

200,000 identification numbers are possible

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 !
