The formula for the volume of a cone is V = PI x r^2 x h/3
r = 1/2 the diameter. 1/2 of 8 = 4 inches.
h = height = 12 inches.
Using 3.14 for PI, the formula now becomes:
V = 3.14 x 4^2 x 12/3
V = 3.14 x 16 x 4
V = 200.96 cubic inches.
You do not say if the answer needs to be rounded, so round the answer as needed.
Answer:
the real solutions are the ones that actually cross the x-axis.
so the real solutions are (-5, 0) (-1,0) (4,0) and (8,0)
Answer:
3 - 4x - 32
Step-by-step explanation:
(3x+8)(x-4)
=3 -12x + 8x -32
=3 - 4x - 32
Answer:
37 million and 37037
Step-by-step explanation:
<h3>Given</h3>
- Current year online retail site visitors = 50 million
- Previous year online retail site visitors = x
- The difference = 35% increase from previous year
<h3>Solution</h3>
- x + 35% = 50 million
- x*1.35 = 50 million
- x = 50 million /1.35
- x = 37 million and 37037
