Answer:
I honestly don't know how to solve anything like this but my best guess is 135
Step-by-step explanation:
I used the area of a circle formula to find the area of the two semi-circles, and then added it to the area of the rectangle. (Once again, I really do not know xD)
We know that
Area circle=pi*r²--------------> r=√(A/pi)
case 1) 221.5584 square units area -------------> r=√(221.5584/pi)=8.398 units
Diameter=2r-----> 2*8.4=16.8 units
case 2) 78.5 square units area-------------> r=√(78.5/pi)=5 units
Diameter=2r-----> 2*5=10 units
case 3) 452.16 square units area -------------> r=√(452.16/pi)=12 units
Diameter=2r-----> 2*12=24 units
case 4) 36.2984 square units area -------------> r=√(36.2984/pi)=3.4 units
Diameter=2r-----> 2*3.4=6.8 units
case 5) 314 square units area -------------> r=√(314/pi)=10 units
Diameter=2r-----> 2*10=20 units
case 6) 886.2336 square units -------------> r=√(886.2336/pi)=16.8 units
Diameter=2r-----> 2*16.8=33.6 units
-3 is the slope, -7 is initial value, x is independent and y is dependent
