Answer:

39.28cm^2

Step-by-step explanation:

area of the circle = 3.142 × radius^2

= 78.55cm^2

area of the semi circle = 1/2 × 78.55

= 39.28cm^2

BRAINLIEST FOR WHOEVER ANSWERS FIRST!!!!

Fofino [41]

Answer:

x = 34

Step-by-step explanation:

ΔABD and ΔBCD are both isosceles triangles

In ΔABD

AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )

∠ABD = $\frac{180-44}{2}$ = $\frac{136}{2}$ = 68°

∠DBC = 180° - 68° = 112° ( straight angle )

∠BCD = x = $\frac{180-112}{2}$ = $\frac{68}{2}$ = 34
