Let’s assume the point in the centre is the origin of the circle.
This means the radius is 21/2 = 10.5cm.
180 - 168 = 12 degrees as the angle between BC.
Circumference of a sector is:
Angle/360 • pi • diameter
=12/360 • pi • 21 cm
= 2.19 cm = 2.20 cm
Which is option B
The correct answer is 10/7 or 1 3/7. Hope this helps.
Answer:
Maxima and minima are+ 4,-4; 2.67,-3; 2.2, -2.6, respectively.
The first and most noticeable wavelengths are 2 m and around 15 m however the 3-and 5-point filters gradually decrease the amplitude of the 2-m wave-length.
Answer:
sec(B)=b. ab/bc
sin(B)=c. ac/ab
csc(B)=f. ab/ac
cot(B)=a. bc/ac
tan(B)=e. ac/bc
cos(B)=d. bc/ab

Answer:
k = 2
Step-by-step explanation:
Fill in the given point values and solve for k.
y = (1/2)x + k
1 = (1/2)(-2) +k . . . . . . for x = -2, y = 1
1 = -1 +k . . . . simplify; next, add 1
2 = k
