They answer D 0 < ; y < 7
Answer:
Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 rad
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Ans: Radius of circle = 17.54 cm

Answer:
y = 4x + 9
week 21
Step-by-step explanation:
first I did 37-9 and got 28 I divide that by 7 ( seven weeks) and got 4 so I know the slope is 4.
so to find how many weeks till 93 I did; 93 = 4x + 9. We have to get x by its self so I minus 9 by both sides and got 84 = 4x. So now we divid both sides by 4 to get x by its self and we end up with 21 = x
Answer:
D - Area = 9/16pi cm²
Step-by-step explanation:
in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.
<u>solution</u>
given that circumference of a circle = 3/2picm
recall that the formula for finding the circumference of a circle = 2πr
3/2picm = 2πr
multiply through by 2
3picm = 4pir
divide both side by 4pi
3pi cm/4pi = r
r = 3/4 picm
Recall that the Area of a circle = πr²
Area = pi ( 3/4)² cm
Area = 9/16pi cm²
