Answer:
Hi.
Step-by-step explanation:
Because this question is asking how much water the water tower can hold, it's asking for the volume of a cylindrical figure. Let's use this formula:
V
=
π
r
2
h
First, let's find our variables by plugging in our information.
r
=
(
1
2
)
d
r
=
(
1
2
)
20
r
=
10
h
=
24
V
=
π
(
10
2
)
(
24
)
Following PEMDAS (Parentheses, Exponents, Multiply, Divide, Add, Subtract), we'll find
(
10
2
)
first.
V
=
π
(
100
)
(
24
)
Now, multiply (100) and (24):
V
=
π
(
2400
)
V
=
2400
π
