Find the volume of a cone with diameter of 12m and a height of 7m
Marysya12 [62]

Answer:

A) 84\pi or approximately 263.76 cubic meters

Step-by-step explanation:

The formula for finding the volume of a cone is V=\frac{1}{3}\pi r^{2} h where V, r, and h are the cone's volume, radius, and height, respectively. We are given that we need to solve for the cone's volume, and we are also given the cone's height, but we don't know its radius. Not to worry though because we are given its diameter, and since radius is simply half of the diameter, we know that the cone's radius is \frac{12}{2}=6 m. Now, we know that r=6 and h=7, so plugging these values into the equation, we get:

V=\frac{1}{3}\pi r^{2} h

= \frac{1}{3} \pi *6^{2} *7 (Substitute given values into equation)

=\frac{1}{3}\pi *36*7\\=84\pi (Simplify)

Since \pi is approximately 3.14, we know that 84\pi =84*3.14=263.76. Therefore, the volume of the cone is 84\pi or approximately 263.76 cubic meters. Hope this helps!

I have attached the picture of the question on this topic.
AVprozaik [17]

Given:

The expression is:

\dfrac{-10v^5x+6v^5x^4}{2v^3x^2}

To find:

The simplified form of the given expression.

Solution:

We have,

\dfrac{-10v^5x+6v^5x^4}{2v^3x^2}

It can be written as:

=\dfrac{-10v^5x}{2v^3x^2}+\dfrac{6v^5x^4}{2v^3x^2}

Cancel out the common factors.

=\dfrac{-5v^2}{x}+3v^2x^2

Therefore, the simplified form of the given expression is \dfrac{-5v^2}{x}+3v^2x^2.
