How do I get the correct answer?

1989.674m³

Step-by-step explanation:

It’s difficult to see the picture, and I can’t read the question.  Are you looking for the volume of the composite shape?  If so:

Cylinder: V=r²h =

Cone: V=r²h/3 =

Hemisphere: V=2/3r³ = 2/3

TOTAL: 1570.796+157.079+261.799=1989.674m³

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
