Volume of cylinder = 1570
Volume of area in box not filled with cylinder
=3550
I’m not sure which one you need, cylinder or shaded area in box, so…
First find volume of cylinder
V= pi r^2 height
V = (3.14) (5^2) (20)
V= (3.14) (25) (20)
V= 1570
Next find TOTAL volume of box
V= Length x width x height
V= 20 x 16 x 16
V= 5120
Now take box (5120) subtract cylinder (1570)
Volume of box not filled with Cyl (shaded area) = 3550
