Find the volume
rectangular solid-/=9 ft.; w=8 ft.; h=7 ft.
cylinder-r=3cm; h=5cm
square pyramid-/=10cm; w=10cm; h=9cm
cone-r=5 in.; h=3 in.
rectangular solid-/=4 1/2 ft.; w=3 ft.; h=2 1/2 ft.

Rectangular Solid: 504 ft cubed

Cylinder: 94.24777960 cm cubed

Square Pyramid: 300 cm cubed

Cone: 78.54 in cubed

Rectangular Solid: 33.75 ft cubed

Step-by-step explanation:

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
