Answer:
1608.5 cm³
Step-by-step explanation:
Use the cylinder volume formula, V =
r²h
If the diameter is 16 cm, then the radius is 8 cm.
Plug in the radius and height into the formula, and solve:
V =
r²h
V =
(8)²(8)
V =
(64)(8)
V = 1608.5
So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³
