The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?

Answers

An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,

V ∝ h(r²)

Also, k is the constant of proportionality, therefore, the equation now can be written as,

V = k×h×r²

Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

x= 32 y= 26

Answers

Answer:

the last one

Step-by-step explanation:

32+26=58

32-26=6

Answer:

The first number is 32 and the second is 26

Step-by-step explanation:

Let the two numbers be represented by x and y

1) x + y = 58

2) x - y = 6

x = 6 + y, we'll use put this in the first equation.

x + y = 58

6 + y + y = 58

6 + 2y = 58

2y = 58 - 6

2y = 52

2. 2

y=26, now let's find x, again use the first equation

x + y = 58

x + 26 = 58

x = 58 - 26

x = 32
