ANSWER: 5 17/23 hrs (5.7391...)

How?
T = 11 hrs
K = 12 hrs
Together = X

1/11x + 1/12x = 1/x

11x/132 + 12x/132 = 132/132

11x x 12x = 23x —> 23x = 132 (divide 132 by 23x)

= 5.73913043 (5 17/23)

Find the area of the shaded regions:
Crank

First, we'll find the area of the large section, including the smaller section that is white.

Area of a circle: pi x r^2

A = pi x 7^2

A = 49pi x 120/360

A = 49/3 pi cm^2

Now, we'll find the area of the small section.

A = pi x 3^2

A = 9 pi x 120/360

A = 3pi cm^2

All that's left to do now is subtract.

49/3 pi - 3 pi

40/3 pi cm^2

(or 13 1/3 = 13.33 cm^2)

Hope this helps!
