Answer:
Approximately, 6.283..
Step-by-step explanation:
First calculate the area of the whole circle
We have radius(r)=4 cm
Area of circle(a)=pir^2
=pi×(4)^2
=pi×16
=Approximately,50.265......
A cirlce has a total of 360 degrees
Therefore,we can conclude 360 degrees=50.265...
or,1 degree=50.265/360
1 degree=Approximately,0.139
Now,
Area for the shaded region = Area of 45 degree
=0.139×45=Approximately,6.283.....
Therefore,the area of the shaded region is approximately,6.283....

Answer:
First choice
Step-by-step explanation:
Angles A and D are vertical angles
Angles A and Z are alternate exterior angles

Using geometric sequence form, we can rewrite it as:


Since r < 1, there exists a limit, and thus, it is said to converge.


Since the ratio is still positive, as n tends towards infinity, the graph of the sequence will never go below the horizontal. Thus, we say that the limit of the function is zero, which means that as we increase the size of n, eventually after the infinite-th time, it will hit zero.
V=7 and v=5 because since it says less than or equal to it has to be a number less than 7 or a number equal to 7
