Suppose f:double-struck Rn → double-struck Rm and g:double-struck Rp → double-struck Rq. (a) What must be true about the numbers
n, m, p, and q for f ∘ g to make sense? n = q m = p n = p m = q n = m (b) What must be true about the numbers n, m, p, and q for g ∘ f to make sense? n = q m = p n = p m = q n = m (c) When does f ∘ f make sense?

Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle =
Here, r = radius of the semicircle
For the semicircle with radius = = 3 units
Area =
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units
