Find the area of a regular hexagon with a side length of 4cm an apothem of approximately 3.5 cm

Mathematics

Gala2k [10]3 years ago

HEXA = 6, 6 sides, thus the hexagon has 6 sides, each side is 4 cm long, thus that gives us a perimeter of 6 * 4 = 24.

\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} a=apothem\\ p=perimeter\\[-0.5em] \hrulefill\\ p=24\\ a=3.5 \end{cases}\implies A=\cfrac{1}{2}(3.5)(24)\implies A=42

I need help finding perimeter of a rectangle with the side missing
3241004551 [841]
The perimeter of a rectangle is  (2 lengths) plus (2 widths).

If one side is missing, then it sounds like you still have enough information
to know what the length and the width are.  Just take each number and use
the first line up there /\ to calculate the perimeter with them.

A) If the 5th term of an A.P. is double the 7th term, show that the sum of the 17 terms zero.​
gayaneshka [121]

Answer:

see explanation

Step-by-step explanation:

The nth term of an AP is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₅ is double a₇ , then

a₁ + 4d = 2(a₁ + 6d) , that is

a₁ + 4d = 2a₁ + 12d ( subtract a₁ from both sides )

4d = a₁ + 12d ( subtract 12d from both sides )

- 8d = a₁

The sum of n terms of an AP is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ] , substitute values

S_{17} = \frac{17}{2} ( 2(- 8d) + 16d)

     = 8.5(- 16d + 16d)

     = 8.5 × 0

     = 0
