Answer:
hello
the answer for questions 5) is:
θ = 30°, R = 6 ft
Arc = CE = Rθ ----> CE = 30 × 6 = 180
and the answer for question 6) is:
square area = A²
big square area = 4 × 4 = 16
small square area = 2 × 2 = 4
circle area = πr²
big circle area = 3.14 × (2)² = 12.56
small circle area = 3.14 × (1)² = 3.14
area of the bigger shaded region = 16 - 12.56 = 3.44
area of the smaller shaded region = 4 - 3.14 = 0.86
