20% = 0.20
6 * 0.20 = 1.2
6 + 1.2 = 7.2
Circle B has a radius of 7.2.
Circle Area = pi *r^2
Lets use 3.14 for pi
3.14 * 7.2^2 = Area of circle B
7.2 * 7.2 = 51.84
3.14 * 51.84 = 162.7776
Area of circle B is 162.7776
Rounded to 2 decimals, this is 162.78
A. 189.31
D. 162.78
E. 203.15
are all equal to or grater than 162.78

Answer:
Step-by-step explanation:
First put the lower limit, i.e., x=0,
F(x)=8cos[2(0)]=8cos(0)=8(1)=8
;cos(0)=1
Now,put the upper limit of given interval, i.e., x = π,
F(x)=8cos[2(π)]=8cos(2π)=8(1)=8
;cos(2π)=1
Answer:
participant bias
Step-by-step explanation:
Participant bias is sometimes called as subject bias. it is referred to as the tendency of a subject that forces them to act in an experiment. it is held because that they think researchers is looking up to them to act. it occurs only when the subject has detail knowledge about the study or project.

Answer:
600 x 60 = 36,000
50 x 50 = 2,500
1,000 x 3 = 3,000
70 x 80 = 5,600
100 x 300 = 30,000
20 x 40 = 800
90 x 90 = 8,100
9 x 900 = 8,100
500 x 300 = 150,000
1,000 x 5 = 5,000
125 - 100
770 - 800
