The radius of circle C is 6 units and the measure of central angle ACB is StartFraction pi Over 2 EndFraction radians. What is the approximate area of the entire circle? square units What is the approximate area of the entire sector created by central angle ACB? square units What is the approximate area of the shaded region only? square units

Step-by-step explanation:

We khow that the radius of our circle is 6

Let A be the area of our cercle :

A= 6^2*Pi = 36 Pi = 113.09 sq.units

We khow that the mesure of our angle ABC is Pi over 2 wich is 90 degree

So this triangle ABC is a right one .

So I think that we must khow the area of this triangle to be able to khow the area of the sector .

We have a hint : ABC is 90 degree so it is the quarter of our cercle

We need to divide the area of the circle by 4

113.09 ÷4 = 28.27

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
