9514 1404 393

  370

Step-by-step explanation:

The set B∩(F∪M) is the sum of the numbers on line B in both the M and F columns:

  B∩(F∪M) = 54 +316 = 370

The set B∩(F∪M) contains 370 respondents.

Area of circle: 3.14r^2

In this case,  the radius is 17. So we have: 3.14(17^2) which is equal to 907.46

To find the shaded area, subtract away the area of the triangle.

Area of triangle = 1/2(bh)

Area = 1/2(16x31)

Area = 8x31, or 248

So our final  answer is 907.46 - 248, making the first choice the correct answer.

659.46yd squared.
