None of the choices XD
-12/5
Bad approximation of π
The better approximation of π: 3.1415926535897932384626433 with 25 decimal places(I recited it XD)
9x+35= -19
9x= -54
x= -6
8.5/π=diameter
area = π(8.5/2π)^2= 5.749cm2
Base length = 10 -6 = 4
Height = 6
Therefore
Area
= 6x4/2
=12 m2
10000 x 5.3% x 4 = 2120
Where is the semi-circle?
Is it above the trapezoid or below the trapezoid?
If above the trapezoid:
\(\frac{4π}{2}+2(6)+10=22+2π\)
If below the trapezoid:
\(\frac{10π}{2}+2(6)+4=16+5π \)
\(\frac{5+6+10+6+10+6}{6}=\frac{43}{6}=7.16666666666667\)
= (2.2÷2) • (-3)
= 1.1 • (-3)
= -3.3
