Please help!!
The Ming family has a backyard kiddie pool with the dimensions shown (Radius-4, Height-2). After a lot of splashing one afternoon, the pool is only half full.
What is the volume of water remaining in the pool?
(Either enter an exact answer in terms of pi or use 3.14 for pi)
Answers
Answer:
50.24
Step-by-step explanation:
Volume of a cylinder = pie x radius^2 x Height
= 3.14 x 16 x 2
= 3.14 x 32
= 100.48
remaining volume = 100.48/2
= 50.24
Answer:
This problem calls for the formula for the volume of a cylinder which is {V}= \pi r^2 hV=πr

hV, equals, pi, r, squared, h.
The pool has a radius of \blueD44start color #11accd, 4, end color #11accd feet and a height of \greenD22start color #1fab54, 2, end color #1fab54 feet.
\begin{aligned} V &= \pi \cdot\blueD4^2 \cdot \greenD2 \\\\ &= \pi \cdot 16 \cdot 2 \\\\ &= 32 \pi\\\\ \end{aligned}
V
=π⋅4

⋅2
=π⋅16⋅2
=32π
Hint #33 / 4
Since half the water has splashed out of the pool, we can divide to find the volume of the remaining water.
\dfrac{32 \pi}{2} = 16 \pi
