A regular hexagon is circumscribed about a circle with a radius of 6. Find the area of the shaded region shown. Give the exact a
Alecsey [184]

Answer:

19.58 unit²

Step-by-step explanation:

To find the area of the shaded region, we use the formula:

A_{shaded}=A_{circle} - A_{hexagon}\\\\

As we know that,

A_{circle} = \pi r^2 = \pi 6^2

           =36πunit²

   

Next is to split up the hexagon into 6 regular triangles.

A_{hexagon} = 6. A_{triangle}

               =6 x \frac{1}{2} bh

the base is equal to the radius i.e 6 as the triangles are regular.The height can be represented by taking one of the triangles and drawing a line down the middle.

So, the newly formed triangle is a 30°-60°90° right triangle.

(see figure 1 in attachment)

Here, a= 6/2=> 3

h= a√3 => 3√3

Substituting the required values in the formula of area of hexagon, we get

A_{hexagon}= 6.\frac{1}{2}.6.3\sqrt{3} => 54√3unit²

A_{shaded}=A_{circle} - A_{hexagon}\\\\

           =36π-54√3

            = 19.58 unit²

What basic trigonometric identity would you use to verify that sinx cosx tanx=1-cos^2x
andre [41]

Answer:

sin^2x+cos^2x=1 is used to prove the given equation.

Step-by-step explanation:

We have given an equation:

sinx\cdot cosx\cdot tanx=1-cos^2x

We will consider right hand side first

tan x can be written as:

tanx=\frac{sinx}{cosx}

So, on substituting tan x in the left hand side of the given equation we get:

sinx\cdot cosx\cdot \frac{sinx}{cosx}

Cancel common term from denominator and numerator which is cosx we get

sin^2x

And we have an identity:

sin^2x+cos^2x=1

\Rightarrow sin^2x=1-cos^2x

Hence, right hand side is equal to sin^2x.
