A pyramid has a regular hexagonal base with side lengths of 4 and a slant height of 6. Find the total area of the pyramid.

denpristay [2]

The area is given by:
A = Ab + Al
Where,
Ab: base area
Al: lateral area
The area of the base is:
Ab = (3/2) * (L ^ 2) * (root (3))
Where,
L: side of the hexagon.
Substituting we have:
Ab = (3/2) * (4 ^ 2) * (root (3))
Ab = (3/2) * (16) * (root (3))
Ab = 24raiz (3)
The lateral area is:
Al = (6) * (1/2) * (b) * (h)
Where,
b: base of the triangle
h: height of the triangle
Substituting we have:
Al = (6) * (1/2) * (4) * (6)
Al = 72
The total area is:
A = 24raiz (3) + 72
Answer:
A = 24raiz (3) + 72

What is the volume of a cylinder, in cubic inches, with a height of 5 inches and a base diameter of 14 inches?

True [87]

Answer:

770 cubic inches (769.69)

Step-by-step explanation:

V = π $r^{2}$ h

r = d/2 = 14/2 = 7 inches

h = 5 inches

V = π * $7^{2}$ * 5 ≈ 769.69 ≈ 770 cubic inches

Answer: $\textsf{Option A, 13}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Side length = 9 units}$

Find: $\textsf{Diagonal length}$

Solution: The diagonal length can be easily determined using an equation which uses the side length of a square multiplied by the square root of 2. All we need to do is plug in the values and simplify the expression.

<u>Plug in the values</u>

$\textsf{Diagonal = Side length} * \sqrt{2}$

$\textsf{Diagonal = 9 units} * \sqrt{2}$

<u>Simplify the expression</u>

$\textsf{Diagonal = 9 units * 1.4142}$

$\textsf{Diagonal = 12.73 units}$

Looking at the answer options that have been provided, the option that best fits our scenario is option A, 13.
