Answer:
320pi cm
Step-by-step explanation:
This problem calls for the formula for the volume of a cylinder which is {V}= \pi r^2 hV=πr
2
hV, equals, pi, r, squared, h.
Hint #22 / 3
The radius of the water bottle is \blueD44start color #11accd, 4, end color #11accd cm and the height is \greenD{20}20start color #1fab54, 20, end color #1fab54 cm.
\begin{aligned} V &= \pi \cdot\blueD4^2 \cdot \greenD{20} \\\\ &= \pi \cdot 16 \cdot 20 \\\\ &= 320 \pi\\\\ \end{aligned}
V
=π⋅4
2
⋅20
=π⋅16⋅20
=320π
