What is the surface area of a cone that has a radius of 8 feet and a slant height of 12 feet?   (use 3.14 for  π.)

301.44 ft  2

502.4 ft  2

200.96 ft  2

803.84 ft  2

Step-by-step explanation:

we know that

The surface area of a cone is equal to

we have

substitute the given values

step-by-step explanation:

if x = 2 you have to find x to finish the problem

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
