The equivalent fraction of 4/20 is 3/15
I would be glad to help you! I will solve through 3 to get you started.
This is a very important concept, so it would be helpful if you learn it on your own.
C= 2* pi* r
1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5
Multiply it by using a calculator.
My answer was 31.4.
Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius.
9/2= 4.5
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26
One more.
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.
Make sure to add the end signs to you answer, ft, cm, meter, etc.
Let me know if you need more help.
Brainliest answer is always appreciated.

Answer with Step-by-step explanation:
We are given that two events A and B are mutually exclusive.
![A\cap B=\phi](https://tex.z-dn.net/?f=A%5Ccap%20B%3D%5Cphi)
![P(A\cap B)=0](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%3D0)
![P(A)\neq 0](https://tex.z-dn.net/?f=P%28A%29%5Cneq%200)
![P(B)\neq 0](https://tex.z-dn.net/?f=P%28B%29%5Cneq%200)
a.For mutually exclusive events,
![P(A/B)=\frac{P(A\cap B)}{P(B)}=\frac{0}{P(A)}=0](https://tex.z-dn.net/?f=P%28A%2FB%29%3D%5Cfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%3D%5Cfrac%7B0%7D%7BP%28A%29%7D%3D0)
Therefore, event A can not occurred if event B has occurred because two events can not occur together.
Answer:No, by definition mutually exclusive events cannot occur together.
b.When two events are independent
Then , ![P(A\cap B)=P(A)\cdot P(B)](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%3DP%28A%29%5Ccdot%20P%28B%29)
![P(A/B)=\frac{P(A)\cdot P(B)}{P(B)}=P(A)](https://tex.z-dn.net/?f=P%28A%2FB%29%3D%5Cfrac%7BP%28A%29%5Ccdot%20P%28B%29%7D%7BP%28B%29%7D%3DP%28A%29)
If two events are mutually exclusive then
![P(A\cap B)=0](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%3D0)
Then , ![P(A/B)=0](https://tex.z-dn.net/?f=P%28A%2FB%29%3D0)
Therefore, ![P(A/B)\neq P(A)](https://tex.z-dn.net/?f=P%28A%2FB%29%5Cneq%20P%28A%29)
Hence, we can concluded that events A and B are not independent if they are mutually exclusive.
Answer:Yes, ![P(A/B)\neq P(A)](https://tex.z-dn.net/?f=P%28A%2FB%29%5Cneq%20P%28A%29)
(x+4)(x-1) which expanded out gives
x^2+3x-4
