6= 2D/5
5 x 6 = 30
30/2D
15=D
I believe the equation should be y = -0.5sin(x-2<span>π)-2</span>

Answer:
volume = 504
Step-by-step explanation:
the basic formula for volume is length × width
14 x 3 x 3 x 2 x 2 = 504
Área of rectangle= 18 x 14 = 252
Area or triangle=
30-18= 12
12 is the base of the triangle
14 is the height of the triangle
Area of a Triangle= 1/2bh
1/2(12)(14)=84
Área of Triangle= 84
252+84= 336
Answer= 336
