Evaluation: Tan 15 degrees / Tan ^ 2 15 degrees - 1 RT~

Tan30 degree = 2tan15 degree / (1 - Tan ^ 2 15 degree) = √ 3 / 3
=Tan 15 degrees / Tan ^ 2 15 degrees - 1 = - √ 3 / 6

Given that the area difference between the inscribed hexagon and the inscribed square of a circle is 11, find the area of the circle?

Two times the root, three minus eleven by two, and then multiply by PI

Given that the area of the inscribed square of a circle is 2, find the area of the circumscribed regular hexagon of the circumscribed regular triangle of the circle

Because the square area is 2, so od = 1, so OC = 2od = 2, so OE = OC = 2, so AF = 2ae = 2 * (OE / root 3) = 4 / root 3, so s

If the area of the large regular hexagon is 10 square meters, then what is the area of the small hexagon?

For the same circle, the similarity ratio of circumscribed hexagon and inscribed hexagon = (radical 3) / 2
The area ratio is equal to the similarity ratio of the bungalow, so, the small hexagon area
=10*3/4=7.5m^2

Area of regular hexagon The side length of a regular hexagon is 12 mm

A regular hexagon is equivalent to the sum of the areas of six equilateral triangles with a side length of 12 mm, and one of the equilateral triangles has an area of 36 roots and 3 square mm
Therefore, the area of a regular hexagon is 216 square millimeters

The length of one side of a hexagon is 8 cm. Find the area of a regular hexagon

The area of a regular hexagon is equivalent to the area of six regular triangles with the same side length;
The area of an equilateral triangle with a side length of 8 = 8 * 8sin60 / 2 = 16 * √ 3;
The area of the regular hexagon is 6 * 16 √ 3 = 96 √ 3 (square centimeter);

How to find the area of a regular hexagon when it is known that there is only a distance between the sides and the center of a regular hexagon

If the edge center distance x
A regular hexagon is composed of six regular triangles
Know that the height of an equilateral triangle is the distance between the sides and the center X
So the s-triangle = root 3 divided by 3 times x squared
S 6 = 2 times the root 3 times x squared

How to calculate the area of a regular hexagon What is the area of a regular hexagon with side length B?

B is the area of the regular six times the length of B
=(3/4)*√3*b*b

Area formula of regular hexagon Given that the side length of a regular hexagon is B, what is its area formula? (please write in detail. It's better not to use some incomprehensible symbols!)

It is divided into six congruent equilateral triangles passing through the center,
The height of an equilateral triangle can be calculated as √ 3 / 2 × B by using Pythagorean theorem
The area of each triangle is √ 3 / 4 × B ^ 2
So the area of a regular hexagon is √ 3 / 4 × B ^ 2 × 6 = 3 √ 3 / 2 × B ^ 2

What is the ratio of the area of an inscribed regular triangle to a regular hexagon?

One to two
