The answer is 162in2 to its orbit
From the given description it seems that the small shaded circle lies within the larger circle as shown in image below:
The probability that a point choosen at random lies within the shaded area = Area of shaded region / Total area of the bigger cricle
So,
Probability = 78.5/314 = 0.25
Thus there is 0.25 or 25% probability that the point chosen at random will lie inside the shaded region.
To convert a percent to a decimal, divide the percent by 100.
0.8/100 = 0.008 <<<<<< answer.
58300 - 8300 - 12750 - 22400 = 14850
We take the total profit (58300) and subtract the value of all 3 contracts to see what is left over. That remaining amount (14850) is the final contract.
