I will find the radius first
2pi(r) = 7pi
Divide 7pi by 2pi
Hence radius is 3.5m
Now the area pi(r^2)
Pi(3.5^2)
The area of the circle is 38.48 or 49/4 pi
AREA = 49/4pi or 38.5m^2 to one d.p
<em>Answer:</em>

I've attached the drawing of my number line to show my thinking. Download to turn it in if you need to.
Have a beautiful day, and stay safe.
Answer:
127°
Step-by-step explanation:
Convert 7 to a fraction with 5 on the bottom
35/5+2/5= 37/5 or 7.4
Answer:
m∡GHI = 21°
Step-by-step explanation:
Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.
That means you can set them equal to each other
x + 7 = 3x - 21
x = 14
Now plug x into GHI
14 + 7 = 21
m∡GHI = 21°
