1. after teaching about the world’s biggest ice cream cone mr. karr decided to make one of his own. approximately how much ice cream will he need to buy? use the dimensions below to find out how much ice cream to purchase. round your answer to the nearest tenth of a cubic inch. use 3.14 to approximate pi.

3.14*9*9*14=3,560.76

3,560.76/3=1,186.92 (3,052.1)

3.14*9*9*4=9,156.24

9,156.24 /3=3,052.08 (3,052.1)

3,052.1+3,052.1=6104.2

but i'm not sure

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.

there still no table
