Area of a semicircle is 1/2* πr^2
Area of a square is s^2
Square’s area: 4mm^2
The radius is 3mm
Plug into the equation
1/2* π(3^2)
1/2* π(9)
We can use 3.14 as an estimate of pi
1/2*28.26
14.13mm^2
Now just add them both
Total area 18.13mm^2
Step-by-step explanation:
∑k=150(3k+2)
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
That would be angle 2. It is on the opposite of angle 7 and it is inside the two parallel lines
Hope this helped!

Answer:
Y=-2/3x+0
This is the answer I found
4/5 - 7/9 + 1/5
(4/5 + 1/5) - 7/9
1 - 7/9
9/9 - 7/9
2/9 <==
