To find median you set up the number least to greasiest and then cross each one out one side at a time until you get to the middle
The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
( 2x +5)^2 =4
2x+5=2
2x=-3
X=-3/2
