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....
242% should be the answer
Answer:
b. 
Step-by-step explanation:

Quadratic equations are suppose to be written as: 
so the new quadratic equation for this problem will be: 
Now rearrange the terms:
Then use the Quadratic Formula to Solve for the Quadratic Equation
Quadratic Formula =
Note: Ignore the A in the quadratic formula
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

a = 3
b = -7
c = -1
