a pyramid has a regular hexagonal base with side length of 4 and a slant height of 6. what is the total area of the pyramid
Stels [109]
So hmm notice the picture below

the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges

now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}\cdot  n\cdot  s^2\cdot  cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of a side}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
n=6\\
s=4
\end{cases}\\\\\\ A=\cfrac{1}{4}\cdot  6\cdot  4^2\cdot  cot\left( \frac{180}{6} \right)

now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both

When a spherical balloon is filled with air, it has a radius of 3 inches. Which of these gives the best estimate for the volume
marysya [2.9K]
By definition, the volume of a sphere is given by:
 V = (4/3) * (pi) * (r ^ 3)
 where,
 r: radius of the sphere.
 Substituting we have:
 V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
 answer
 the best estimate for the volume of air in the balloon in cubic inches is
 C. 113.1

Can you identify a parallel or perpendicular equation and type the correct code?
AlladinOne [14]

Answer:

The equation of the line that is parallel to  is  and the equation of the line that is perpendicular to  is .

Let be a line whose equation is:

(1)

Whose explicit form is:

(2)

Where:

- Independent variable.

- Dependent variable.

The slope and x-intercept of the line are  and , respectively.

There are two facts:

A line is parallel to other line when the former has the same slope of the latter.

A line is perpendicular to other line when the former has a slope described the following form (), where  is the slope of the former.

Then, the equation of the line that is parallel to  is  and the equation of the line that is perpendicular to  is .
