A half cone has a diameter of 10 and a height of 8. What is the approximate volume of the half cone? Round to the nearest tenth where necessary.

step-by-step explanation:

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

2+2 obliviously is 4.

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
