Match the formula to the correct figure.

forsale [732]

Given:

The figures cylinder, cube, cone, and pyramid.

To find:

The formula of volume for the given figures.

Solution:

Volume of a cylinder is:

$V_1=\pi r^2h$

Where r is the radius and h is the height.

Volume of a cube is:

$V_2=a^3$

Where a is side length of cube.

It is also written as:

$V_2=l\times w\times h$

Where l is length, w is width, h is height and $l=w=h$ .

Volume of a cone is:

$V_3=\dfrac{1}{3}\pi r^2h$

Where r is the radius and h is the height.

Volume of a pyramid is:

$V_4=\dfrac{1}{3}Bh$

Where B is the base area and h is the height.

Therefore the table of formulae is shown below:

Figure Volume formula

Cylinder $\pi r^2h$

Cube $l\times w\times h$

Cone $\dfrac{1}{3}\pi r^2h$

Pyramid $\dfrac{1}{3}Bh$

If h (r)= 2/3 r - 6, what is the value of h(-9)?

Bad White [126]

Answer:

$h(-9)=-\frac{2}{33}$

Step-by-step explanation:

The given expression is $h(r)=\frac{2}{3r-6}$

We want to find the value of h(-9).

We substitute r=-9 to obtain:

$h(-9)=\frac{2}{3(-9)-6}$

We multiply out to obtain:

$h(-9)=\frac{2}{-27-6}$

We simplify the denominator to obtain:

$h(-9)=\frac{2}{-33}$

This is the same as:

$h(-9)=-\frac{2}{33}$
