Somebody pls what is the approximate area

20.36

Step-by-step explanation:

The area of the whole circle is pi*3.6^2 = 40.715 (rounded).  However, the shaded portion is only half of the circle, since the arc is 180 degrees, so we divide this by 2 to get about 20.36.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
