Easy. Remember that 100% of the circle is 360 deg
1. Calculate the total area, pi * radius^2
2. Divide the angle of the area you want by 360 and then multiply by the area in 1.

2) Which is the shaded region the triangle or the circle?
Area of the circle = pi times radius^2
Area of the triangle = 0.5 times radius^2 times sine(of given angle)
If the shaded area is the circle then it is: area of circle  area of triangle

I'm assuming the "shaded area" is the slice of pie for each case. In which case:
a) A = pi r^2 for the whole pie and a = theta/360 * A = 70/360*pi()*6^2 = 21.99 cm^2 ANS.
b) = (104/360)*pi()*14^2 = 177.9 cm^2 ANS
c) = (80/360)*pi()*5^2 = ? ANS you can do the math.

2. a. area of sector= 70/360 * π*6² ≈ 21.99 cm²
area of triangle= 6sin35° * 6cos35°≈ 16.91 cm²
area below the triangle= 21.99  16.91= 5.08 cm²

It looks like the only shaded area is half of question 3. Looks like a trick question.
