Answer:
![d = \frac{C}{\pi}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7BC%7D%7B%5Cpi%7D)
Step-by-step explanation:
![C= \pi d\\](https://tex.z-dn.net/?f=C%3D%20%5Cpi%20d%5C%5C)
Isolate d ; Divide both sides of the equation by ![\pi](https://tex.z-dn.net/?f=%5Cpi)
![\frac{C}{\pi} = \frac{\pi d}{\pi }](https://tex.z-dn.net/?f=%5Cfrac%7BC%7D%7B%5Cpi%7D%20%3D%20%5Cfrac%7B%5Cpi%20d%7D%7B%5Cpi%20%7D)
Simplify
![\frac{C}{\pi} = d\\\\d = \frac{C}{\pi}](https://tex.z-dn.net/?f=%5Cfrac%7BC%7D%7B%5Cpi%7D%20%3D%20d%5C%5C%5C%5Cd%20%3D%20%5Cfrac%7BC%7D%7B%5Cpi%7D)
Note; Another formula for d(diameter) =
![2\times radius](https://tex.z-dn.net/?f=2%5Ctimes%20radius)
The exponent tells you how many places to move.
Answer:
There are only 3 differences perform
Step-by-step explanation:
I. If x is negative, y is negative then the answer is possitive
eg. x is -2, y is -3
-2 × -3 = 6
II. If x is negative, y is positive then the answer is negative
eg. x is -1, y is 2
-1 × 2 = -2
III. If x is possitive, y is possitive then the answer is positive
eg. x is 2, y is 5
2 × 5 = 10
Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.
