C it’s what I chose for it
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....
If the 2 given points are endpoints, then we're in business. The formula for the midpoint is
. If the endpoints of our segment are the coordinates (1,2) and (12,14), our formula would be filled in as follows:
which simplifies to (13/2, 8). See? It's pretty simple once you know how to do it.
The function f(x) = -5x³ + 3x² + x - 9 is a cubic function with the form:
f(x) = ax³ + bx² + cx + d, where a = -5, dictates the end behavoir of the function.
Since a is negative, then as x → -∞, y → ∞, and as x → ∞, y → -∞.
4 divided by 5 is equal to 0.8. This decimal can also be written as a fraction. 0.8 = eight tenths or 8/10 (4/5 in its reduced form).
