Answer:
The only difference is that we line up the numbers according to the decimal point. For addition, it doesn't matter which number goes on the bottom.

4 is the greasy common factor
Answer:
hi I was wondering if I could come in
Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
![s=r \theta](https://tex.z-dn.net/?f=s%3Dr%20%5Ctheta)
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:
![s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4](https://tex.z-dn.net/?f=s%3Dr%5Ctheta%5C%5C20%3D5%5Ctheta%5C%5C%5Ctheta%3D%5Cfrac%7B20%7D%7B5%7D%5C%5C%5Ctheta%3D4)
This is given in radians, so
is 4 radians
D is the correct answer choice.
