Answer:
Area of parallelogram is equal to the product of base and height, the area is the product of [tex]\pi r[/tex] and r, or [tex]\pi r^{2}[/tex].
Step-by-step explanation:
We are finding the area of a circle by an alternative method.
What we do is split the circle into multiple sectors and then arrange them in the form of a parallelogram and find the area of this parallelogram.
Area of parallelogram = base[tex]\times height[/tex]
Hence area is the product of base and height.
Base = [tex]\pi r[/tex]
Height = r
Area is the product of [tex]\pi r[/tex] and r = [tex]\pi r^{2}[/tex]
