What numbers do you need to determine the surface area of a right cone? ANSWERS: The radius of the base, r, and the altitude h. The altitude h and the slant height s. The radius of the base, r, and the slant height s. You must have all three numbers r, s, and h.

The Radius of the base, r, and the altitude h

Step-by-step explanation:

Surface area of a right cone

R= Radius

H=Radius

she drove 134 miles

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.
