Answer:
volume cone = 1/3 pi r^2 h
volume cylinder = pi r^2 h
Step-by-step explanation:
1. Volume = 1/3 x pi x r^2 x h = 12 X pi
2. 100 pi = 1/3 x pi x r^2 x 12
r^2 = 25
r = 5 cm
3. volume = pi x 16 X 5 = 80 pi cubic meters
4. 400 pi = pi x r^2 X 4
r^2 = 100
r = 10 yards
Answer:
yes it is.
Step-by-step explanation:
Answer:
x=-2 x=-1
Step-by-step explanation:
f(x)=x² +3x+2
Set the function equal to zero
0=x² +3x+2
Factor
What 2 numbers multiply to 2 and add to 3
2*1 = 2
2+1 = 3
0 = ( x+2) (x+1)
Using the zero product property
x+2 =0 x+1 =0
x=-2 x=-1
Answer:
<em>Centimeters of crystal ( in real life ) = 0.5 cm</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
1. Given the information, let us create a proportionality as such:
24 = 1 ⇒ x - <em>crystal size in real life</em>
12 x
3. Now let us cross multiply, and solve through simple algebra:
12 = 24 * x,
<em>x = 0.5 centimeters of the crystal in real life</em>
