<h3>
Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
The -9 stays the same the whole time but the other number being multiplied decreases by one each layer, so the next three would be:
-9 x -1 = 9
^^^ -1 is in the second multiplication slot bc 0 - 1 = -1
-9 x -2 = 18
^^^ -2 is in the second multiplication slot bc 0 - 2= -2
-9 x -3 = 27
^^^ -3 is in the second multiplication slot bc 0 - 3 = -3
***Remember that when you are multiplying two negative numbers the solution will be positive
Hope this helped!
I believe the answer is 1/3 because 1 represents the spin and 3 for your chances to land on blue
