Answer:
21.8
Step-by-step explanation:
hii so basically first we find the area of the 9 by 8 and subtract the area of the semicircles.
area of circles are πr^2, so in this situation
π4^2 which is 16π.
with this, the semicircle which is half a circle would give us
16π/2 which is 8π.
but then, we have two semicircles removed so we would have as an answer:
(9*8)-8π+8π
72-16π
then you would have to round so
16π is around 50.2
so 72-50.2 is 21.8
i hope this helped you <33

Step-by-step explanation:
1. 5(1+9v)=5+5x9v=5+(5x9v)=5+45v
2.(20:4/12:4)=4(5b+3)
Hello,
b = 26°
( 26° × 2 ) + 2a = 360°
52° + 2a = 360°
2a = 360° - 52° = 308°
a = 308° / 2 = 154°
A way to write this would be:
100 - e = 42
