The volume of a cylinder is V= πr^2 h.How many variables are there in this formula for v?
Answers
Answer:
a) variables:
V
,
r
,
h
; constants:
π
b) i)Make the radius constant; ii) Make the height constant
c) Let
r
=
h
Explanation:
Given:
V
=
π
r

h
a) Variables are:
V
=
volume
r
=
radius
h
=
height

b) Linear equations are equations of lines.
They have an equation of the form:
y
=
m
x
+
b
; where
m
=
slope;
b
=
y
-intercept
(
0
,
b
)
Notice that there isn't any

i) Make the radius constant. Ex.
r
=
2
⇒
V
=

Quadratic equations have the form:
A
x
2
+
B
x
+
C
=
0
; where
A
,
B
,
and
C
are constants.
The word quadratic in Latin means "square-like".
A simple squaring function is
y
=
A

ii) Make the height constant.
Ex.
h
=
5
⇒
V
=
π
r

where
A
=

c) If
r
=
h
, the equation changes to
V
=
π
