A ring-shaped region is shown below. Its inner radius is 19 m, and its outer radius is 24 m. Find the area of the shaded region. Use 3.14 for . Do not round your answer.

675.1 sq m

Step-by-step explanation:

Area of larger circle = 3.14(24^2) = 3.14(576) = 1808.64

area of smaller circle = 3.14(19^2) = 3.14(361) = 1133.54

area of ring = Area of larger circle - area of smaller circle

= 1808.64 - 1133.54 = 675.1

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.

okay..i will pick 8!
