Well.
The relation between the circumference of a circle and its diameter is described by the following equation:
![Thecircumference=\pi d](https://tex.z-dn.net/?f=%20Thecircumference%3D%5Cpi%20d)
where d is the diameter of the circle.
For a giving diameter (d=3ft), we can substitute in the previous equation
The circumference of a circule= 3.14*3 (you can use ur calculator to find the exact number i guess it will be about 9.42 ft)
I hope it helps.
The value of log(0.47) after rounding to 4 decimal place is -0.3279
Option D
Given :
Find the value of log(0.47) using calculator
To find the log value we use the calculator
here we are asked to find out log (0.47) that is the log (decimal)
we cannot find the log value without calculator because we have decimal argument inside log.
Use scientific calculator
Press log first then enter the number 0.47 inside a parenthesis
Press enter , it will show you the log(0.47)
log(0.47) =-0.327902142
Now round the answer to 4 decimal places
We have 0 in the 5th decimal place . so we keep 9 as it is
log(0.47) =-0.3279

Answer:
P(A or B) is 0.72
Step-by-step explanation:
Given : P(A) = 0.3 and P(B) = 0.6
To Find:P(A or B) = P(A∪B)
Solution :
We are given that A and B are two independent events
Property : If A and B are independent events then ![P(A \cap B) = P(A) \times P(B)](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20P%28A%29%20%5Ctimes%20P%28B%29)
So, ![P(A \cap B) = P(A) \times P(B)](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20P%28A%29%20%5Ctimes%20P%28B%29)
![P(A \cap B) =0.3 \times 0.6](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D0.3%20%5Ctimes%200.6)
![P(A \cap B) =0.18](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D0.18)
Formula : ![P(A \cup B)=P(A)+P(B)-P(A \cap B)](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%3DP%28A%29%2BP%28B%29-P%28A%20%5Ccap%20B%29)
![P(A \cup B)=0.3+0.6-0.18](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%3D0.3%2B0.6-0.18)
![P(A \cup B)=0.72](https://tex.z-dn.net/?f=P%28A%20%5Ccup%20B%29%3D0.72)
Hence P(A or B) is 0.72
