What is the volume of a sphere if it has a radius of 2 feet? (use 3.14 for π .) 33.49 ft 3 100.48 ft 3 75.36 ft 3 25.12 ft 3

33.49

Use this formula:

V = 4/3 • \pi • r^3

V = (4/3) (3.14) (2)^3

V = 33.49

the answer is 45 i just did it on oddesy ware

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.
