The picture shows a circle divided into 8 equal wedges which are rearranged. Figure
The radius of the circle is r
and its circumference is
Π2
. How does the picture help to explain why the area of the circle is
Π2

Because there is 8 wedges and when you turn them around they turn into a equal circle

Step-by-step explanation:

put all the wedges into a circle and there you go

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
