The numbers 1, 2, 3, 4, 5, and 6 are placed in a line. How many even numbers can be made from these digits?

<h3>Answer:    360</h3>

==========================================================

Explanation:

We have 3 even values (2,4, and 6) so this is the number of choices we have for the units digit. Recall that a number is even if the units digit is 0,2,4,6 or 8.

Once we have the units digit selected, we have 6-1 = 5 choices for the first slot, 6-2 = 4 choices for the second slot, and so on until we get down to 6-5 = 1 choice for the fifth slot

We could write it out like this

  • slot one = 5 choices
  • slot two = 4 choices
  • slot three = 3 choices
  • slot four = 2 choices
  • slot five = 1 choice
  • slot six = units digit = 3 choices

Multiply those values out: 5*4*3*2*1*3 = 360

There are 360 different even numbers possible.

Either my brain is straight up goneskiis or I need assistance.
olga nikolaevna [1]
The answer is C. 89 in^2

This is found by (1/2(\pi  r^{2}))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!
