Area of the Base = 6 * side^2 / 4 * tan (180/6)
Area of the Base = 6 * 16 / 4 * 0.57735
Area of the Base = 96 / <span> <span> <span> 2.3094 </span> </span> </span>
Area of the Base = <span> <span> <span> 41.5692387633 </span> </span> </span>

Area of 1 Face = 2 * 6 = 12
Area of 6 Faces = 72

<span> <span> Total Area = 41.5692387633 </span> + 72</span>
Total Area = 113<span>.5692387633</span>

Answer:

Step-by-step explanation:

alright lets get started.

Total area of pyramid will be equals to the sum of area of base and the area of all six faces.

area of hexagonal will be = \frac{3\sqrt{3} }{2} *a^2

Plugging the value of a as 4, the area of base will be :

\frac{3\sqrt{3} }{2}*4^2= 41.57

Now the area of one face will be= \frac{1}{2} *base*height

so, the area of one face will be = \frac{1}{2} * 4*6=12

So, the area of six faces will be = 6*12=72

So, the total area of pyramid will be = 41.57+72

So, the total area of pyramid will be 113.57

Hence the answer is 113.57.      :   answer

Hope it will help :)

if the equation x^2 +(k+2)x+2k=0 has equal roots,then the value of k is .....a.2 b.-2 c 1/2 d.none ​
blsea [12.9K]

Answer:

k=2

Problem:

if the equation x^2 +(k+2)x+2k=0 has equal roots,then the value of k is ..

Step-by-step explanation:

Since the coefficient of x^2 is 1, we can use this identity to aid us: x^2+bx+(b/2)^2=(x+b/2)^2.

So we want the following:

[(k+2)/2]^2=2k

Apply the power on the left:

(k+2)^2/4=2k

Multiply both sides by 4:

(k+2)^2=8k

Expand left side:

k^2+4k+4=8k *I used identity (x+c)^2=x^2+2xc+c^2

Subtract 8k on both sides:

k^2-4k+4=0

Factor using the identity mentioned a couple lines above:

(k-2)^2=0

Since zero squared is zero, we want k-2=0.

Adding both sides by 2 gives k=2.
