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

Answer:
Step-by-step explanation:
Direct proportional:
Multiplication
Inverse proportional:
Division
The gravitational attraction F between two objects of masses m1 and m2 is jointly proportional to the masses
This means that:
Inversely proportional to the square of the distance r between the objects.
Denominator is . Thus:
Answer:
Step-by-step explanation:
Base = 5 units
Altitude = 2 units
Hypotenuse² = base² + altitude²
Hypotenuse² = 5² + 2²
= 25 + 4
= 29
Hypotenuse = √29 units
