Exercise #1
A hexagon has sides measuring 10cm long. What is the area of the hexagon?
Step-by-Step Solution
The formula to find the area of a regular hexagon with side length s is given by:
233s2
For a hexagon with side length 10 cm, substitute s=10 into the formula:
Area=233×102
Calculate 102:
102=100
Substitute back:
Area=233×100
This simplifies to:
259.81 cm2
Answer:
259.81 cm²
Exercise #2
A hexagon has sides measuring 8cm long. What is the area of the hexagon?
Step-by-Step Solution
The formula to find the area of a regular hexagon with side length s is given by:
233s2
For a hexagon with side length 8 cm, substitute s=8 into the formula:
Area=233×82
Calculate 82:
82=64
Substitute back:
Area=233×64
This simplifies to:
166.28 cm2
Answer:
166.28 cm²
Exercise #3
Given the hexagon in the drawing:
What is the area?
Step-by-Step Solution
To determine the area of the hexagon, follow these steps:
Step 1: Recognize the provided numeral "9" as representing the diameter of the hexagon.
Step 2: Convert the diameter to a radius by dividing by 2. Thus, the radius r=29=4.5.
Step 3: Use the regular hexagon area formula with the radius: A=233r2.
Now, we compute the area using the formula:
Step 3: Plugging in the radius, we have: A=233(4.5)2.
First, calculate (4.5)2=20.25.
Now calculate A=233×20.25.
The approximate value of 3 is 1.732. Continue the calculation: A=23×1.732×20.25≈25.196×20.25≈2.598×20.25≈52.61.
This calculation contrives that the area calculation changed after correction:
The area of the hexagon is ≈52.61.
Therefore, the correct choice is the area: 52.61.
Answer:
52.61
Exercise #4
Given the hexagon in the drawing:
What is the area?
Step-by-Step Solution
To solve this problem, we'll proceed with the following steps:
Step 1: Interpreting the given measure as the diameter of the hexagon and finding the radius.
Step 2: Calculate the side length using the radius.
Step 3: Determine the area using the formula for a regular hexagon.
Here's the detailed process:
Step 1: The given length of 14 is the diameter of the hexagon, which means the diagonal from one vertex, passing through the center, to the opposite vertex. The radius (r) from the center to a vertex would be half of this diameter:
r=214=7
Step 2: The side length s for a regular hexagon is related to the radius by the central triangle consistency (equilateral triangles formed by connecting the center). The side length is equal to the radius:
s=r=7
Step 3: Now, use the formula for the area of a regular hexagon:
Area=233s2
Substitute the side length calculated:
Area=233⋅72
Area=233⋅49
Area=233⋅49≈127.3
Therefore, the area of the hexagon is approximately 127.3. This matches choice 2 in the list of possible answers.
Answer:
127.3

Exercise #5
Below is a hexagon that contains a rectangle inside it.
The area of the rectangle is 28 cm².
What is the area of the hexagon?
Step-by-Step Solution
Since we are given the area of the rectangle, let's first work out the length of the missing side:
7×a=28
We'll now divide both sides by 7 to get:
a=4
Since all sides are equal in a hexagon, each side is equal to 4.
Now let's calculate the area of the hexagon:
46×a2×3
46×42×3
Finally, we simplify the exponent in the denominator of the fraction to get:
6×4×3=24×3=41.56
Answer:
41.56

Frequently Asked Questions
Everything you need to know about Regular polygons - Advanced
What is the formula for calculating the area of a regular hexagon?
+
The area of a regular hexagon is A = (6a²√3)/4, where 'a' is the length of one side. This formula works because a regular hexagon can be divided into 6 congruent equilateral triangles, each with area (a²√3)/4.
How do you find the side length of a hexagon when given the area?
+
To find the side length from area, rearrange the formula: a = √(4A/(6√3)). First multiply the area by 4, then divide by 6√3, and finally take the square root of the result.
What are the interior and exterior angles of a regular hexagon?
+
A regular hexagon has interior angles of 120° and exterior angles of 60°. The sum of all interior angles is 720°, which equals (6-2) × 180°.
How do you calculate hexagon area from perimeter?
+
Steps to find area from perimeter: 1) Divide perimeter by 6 to get side length, 2) Apply the area formula A = (6a²√3)/4, 3) Substitute the side length and calculate.
Why does a regular hexagon divide into 6 triangles?
+
Drawing lines from the center to each vertex creates 6 congruent isosceles triangles. Each triangle has a central angle of 60°, making them equilateral triangles with area (a²√3)/4.
What makes hexagon area problems challenging for students?
+
Common challenges include: working with square roots and radicals, rearranging the area formula to solve for side length, converting between different given measurements (perimeter vs. side), and managing algebraic manipulation in complex problems.
How do you solve hexagon problems with radical expressions?
+
When areas involve radicals like (√3)³: 1) Simplify the radical expression first, 2) Set up the equation A = (6a²√3)/4, 3) Solve algebraically by isolating a², 4) Take the square root to find the side length.
What real-world applications use regular hexagon area calculations?
+
Hexagon areas are used in: architecture and tile design, engineering for bolt patterns and structural elements, biology for honeycomb cell calculations, and manufacturing for hexagonal nuts and fasteners.
