$r=32\,\text{units}\\\\
A=\pi\cdot r^2=\pi\cdot32^2=1024\pi\,\,\text{units}^2$

Answer D.

2.
From secant theorem, we know, that:

$|AE|\cdot|BE|=|DE|\cdot|CE|$

and from picture:

$|BE|=x+1\\\\|CE|=x+4\\\\|AE|=11+x+1=x+12\\\\|DE|=1+x+4=x+5$

So we can calculate:

$|AE|\cdot|BE|=|DE|\cdot|CE|\\\\(x+12)\cdot(x+1)=(x+5)\cdot(x+4)\\\\
x^2+12x+x+12=x^2+5x+4x+20\\\\
x^2+13x+12=x^2+9x+20\quad|-x^2\\\\13x+12=9x+20\quad|-9x\\\\4x+12=20\quad|-12\\\\4x=8\quad|:4\\\\\boxed{x=2}$

Answer:

x = 88.463°

Step-by-step explanation:

We are given a trigonometric equation and we need to find out the value of x. The angle x lies between 0° and 360° . That is ,

$\rm\implies\red{ 0^0 < x < 360^0 }$

Given trigonometric equation :-

$\rm\implies\red{ 1 + 5 sin (x-100^0)=0 }$

Subtracting 1 both sides , we have ,

$\rm\implies 5sin( x - 100^0)= -1$

Divide both sides by 5 ,

$\rm\implies sin( x - 100^0)= \dfrac{-1}{5}$

This equation can be written as ,

$\rm\implies x - 100^0 =sin^{-1}\bigg(\dfrac{ -1}{5}\bigg) \\\\\rm\implies x - 100^0 = -11.53^0 \\\\\rm\implies x = 100^0-11.53^0\\\\\rm\implies\boxed{\bf x = 88.463^0}$
