Answer:
Volume = 200.96 cubic feet
Step-by-step explanation:
Volume of a cone is given by the formula 
Where r is the radius and h is the height
Given r = 4 and height is 3 times that. So height is 4*3 = 12
Plugging these into the formula we get:
Volume of Cone = 
Thus, Volume = 200.96 cubic feet
If you have
y = 3/5 x + 4 you need to multiply by 5 - no fractions
5y = 3x + 20
5y - 3x = 20
-3x +5y =20, 3x -5y =-20
(ax + by = c)
The sum of the prime numbers 2, 5, and 61 is 68.
The answer should be<span> 4. Because in each cube you take from one corner,it seems like you lost 3 square shaped area but when you remove the cube, there occurs the hidden 3 square shaped area under that cube. So the surface area doesn't change. You should try to imagine the cube, it may help. </span>
