Answer:
x=1
Step-by-step explanation:
We know that
[the area of composite figure]=[area of rectangle]+[area of a half circle]
[area of rectangle]=b*h
where
b=the base
h=the height
[area of rectangle]=b*h--------> 4.1*8.6---------> 35.26 cm²
[area of a circle]=pi*r²
where
r=the radius
r=4.1/2-------> 2.05 cm
the figure is a half circle
then
[area of a half circle]=pi*r²/2--------> pi*2.05²/2--------> 6.60 cm²
[the area of composite figure]=35.26+6.60--------> 41.86 cm²
the answer is
41.86 cm²

Answer:
-17/10 ( or 1 7/10)
Step-by-step explanation:
-2 1/8 ÷ 1 1/4 (convert into improper fractions)
= (-17/8) ÷ (5/4)
= (-17/8) x (4/5)
= - (17 x 4) / (8 x 5)
= -68/40
= -17/10 ( or 1 7/10)
