Assuming that this field is rectangular with 2 semi-circles (one on both ends of the field), we must first calculate the total area of the field. this is done by adding the area of the rectangular portion and the circular portion. This is done below:
Area of rectangle = length * width = 95 * 49 Area of rectangle = 4655 yd^2
The area of the 2 semi-circles can be obtained by treating both as one circle. Area of circle = pi * (d/2)^2 = 3.1416 * (49/2)^2 Area of circle = 1885.74 yd^2
Total area = 1885.74 + 4655 = 6540.74
We multiply the area by the cost of fertilizing: Total cost = cost per sq. yd * total area Total cost = 0.08 * 6540.74 Total cost = $523.26
Here are the outcomes. You could also a tree diagram for this:
There are 49 outcomes for this problem. Therefore, 7/49 possible probability that 2 could be orange. To check if i'm correct, use a tree diagram or a compound principle.
