10.1 area of parallelogram and trapezoids
Parallelogram = A=bh
The base of a parallelogram is any side length
Trapezoid = A=1/2(b1+b2)h
the two side that are parallel are the bases of a trapezoid
Parallelogram
A=6*2.5
A=15
Trapezoid
A=1/2(12+6)4
A=7.5+3*4
A=10.5*4
A=42
Real life Trapezoid
Buildings can be a parallelogram
Same with bags
10.2 Area Of Circles
10.2 Formulas and how to solve
r=radius
c=Circumference
A=pi*2^2
A=pi*r^2
A=3.14(5)2
A=78.5
c=pi*d
c=pi*d
c=3.14*24
c=75.36
c-=2*pi*r
c=2*pi*r
c=2*3.14*36
c=226.08
