The dimension of an aquarium are 12 inches * 6 inches * 8 inches. The water in it has a height of 7 inches.
If the same water is poured into a cylindrical container with a diameter of 40 centimeters what would be the height of the water in the cynical container.
Answer choices:
1.64 cms
1.8 cms
6.57 cms
7.51 cms

11 feet 6 inches and 8 feet 6 inches

22

step-by-step explanation:

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.
