What is the surface area of the regular pyramid given below ?

Levart [38]

Answer:

Option C $207\ units^{2}$

Step-by-step explanation:

we know that

the surface area of a pyramid is equal to

$SA=B+LA$

where

B is the area of the base

LA is the lateral area

The area of the base B is

$B=9*9=81\ units^{2}$

The lateral area is equal to

$LA=4*(1/2)(9*7)=126\ units^{2}$

the surface area is equal to

$SA=81+126=207\ units^{2}$

Substitute $u=x^2+4$ and $du=2x\,dx$ . Then the integral transforms to

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \int \frac{du}{u^3}$

Apply the power rule.

$\displaystyle \int \frac{du}{u^3} = -\dfrac1{2u^2} + C$

Now put the result back in terms of $x$ .

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \left(-\dfrac1{2u^2} + C\right) = -\dfrac1{4u^2} + C = \boxed{-\dfrac1{4(x^2+4)^2} + C}$
