Khan uses 78ft of fence for a pen and the length is 25ft. What is the width

mariarad [96]

Answer:

The width is 14ft

Step-by-step explanation:

Given

$Fence = 78$

$Length = 25$

Required

Determine the width

To do this, we assume that the fence is a rectangle

So, we use the following formula.

$Perimeter = 2 * [Length + Width}$

Where:

$Perimeter = Fence = 78$

So, we have:

$78= 2 * [25 + Width}$

Divide both sides by 2

$39= 25 + Width$

Solve for Width

$Width = 39 - 25$

$Width = 14$

The surface area of the cone is 43.75pie cm^2. What is the slant height of the cone and the diameter is 5

Masteriza [31]

If the diameter of the cone is 5, then the radius of it will be half that, or 2.5, thus

$\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
------\\
SA=43.75\pi \\
r=2.5
\end{cases}
\\\\\\
43.75\pi =\pi (2.5)\sqrt{r^2+h^2}+\pi (2.5)^2
\\\\\\
43.75\pi -\pi (2.5)^2=2.5\pi \sqrt{r^2+h^2}
\\\\\\
43.75\pi -6.25\pi =2.5\pi \sqrt{r^2+h^2}\implies 37.5\pi =2.5\pi \sqrt{r^2+h^2}
\\\\\\
\cfrac{37.5\pi }{2.5\pi }=\sqrt{r^2+h^2}\implies 15=\sqrt{r^2+h^2}$
