Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians

86 = 1/2 * r^2 * pi/4

r^2 = 2 * 86 * 4 / pi = 219

r = sqrt 219

= 14.80

You lay out the triangle formula for area which would be A=(1/2)(b)(h)
plug in for variables
375=(1/2)(23.8)(b)
solve for b

SOLUTION

The total number of females =

$19$

if 14 have an A in the class, the number of students without A is:

$29-14=15$

8 male students do not have an A, therefore the number of female students without an A is:

$15-8=7$

The probability that a student does not have an A given that the student is female can be calculated thus:

$\frac{\text{Total number of female students without an A}}{Total\text{ number of female students in the class}}$ $\frac{7}{19}$
