there is 20 in each roll 410/20 is 20.8.
Use elimination method to get -8
Okay, first we need to calculate the area of the rectangle.
Area of Rectangle- 16 x 6 = 96
Next, we need to calculate the area of the semicircles.
Formula: Radius x Radius x pi (3.14) = Area of circle
Since we know that the diameter is 6 we can figure out the radius.
The radius is half of the diameter. So our radius is 3.
3 x 3 x 3.14 = 28.26
Since it's a semi circle we now need to divide by 2.
28.26 divided by 2 = 14.13
Then, we add.
Area of rectangle
+
Area of 2 semi circles
96 + 14.13 + 14.13 = Total Area of The Figure
So our answer is 124.26
