Answer:
C=6π
Step-by-step explanation:
It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.
If identical, it means that the radius of both circles are same i.e.
Radius of both circles is 2(1.5)=3
The circumference of a circle is given by :
So, the circumference of each circle is 6π.
Answer:
Step-by-step explanation:
Answer: The value of c would be 26.514 lb.
Step-by-step explanation:
Since we have given that
Mean = 17 lb
Standard deviation = 3.3 lb
At 99% level of significance, z = 2.58
So, it becomes,
So, the weight c would be
Hence, the value of c would be 26.514 lb.
<u>Answer:</u>
According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .
Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases
