A pipe manufacturer makes pipes of four different sizes. The diameter of each pipe is two times the diameter of the pipe of the next smaller size. The diameter of the biggest pipe is 16 centimeters.
What is the diameter of the pipe of the smallest size?
16/2 = 8
8/2 = 4
4/2 = 2
2/2 = 1
16/2=8
To find the diameter of the smallest pipe, we can work backwards by dividing the diameter of the biggest pipe by 2 each time.
Let's start with the diameter of the biggest pipe, which is 16 centimeters.
Dividing 16 by 2 gives us 8. So, the diameter of the second biggest pipe is 8 centimeters.
Dividing 8 by 2 gives us 4. So, the diameter of the third biggest pipe is 4 centimeters.
Dividing 4 by 2 gives us 2. So, the diameter of the smallest pipe is 2 centimeters.
Therefore, the diameter of the pipe of the smallest size is 2 centimeters.
