Answer:
686 crystals.
Step-by-step explanation:
You can set up an algebraic equation to find the answer.
Let x represent the number of crystals Lily uses.
The question is asking how many crystals it will take to raise 6,174 zombies, when each crystal raises 9.
9x = 6174
x = 6174 / 9
x = 686
That means it will take Lily 686 dark power crystals to raise 6,174. That's a lot of dark power!
Hope this helps!
The answer would be 2.273*10^-3

Answer: 24pi feet</h3>
Work Shown:
The area is 144pi square feet. So A = 144pi is plugged into the formula below to isolate r
A = pi*r^2
144pi = pi*r^2
144 = r^2 .... divide both sides by pi, the pi terms cancel
r^2 = 144
r = sqrt(144) ... take the square root of both sides
r = 12
This is plugged into the circumference of a circle formula
C = 2*pi*r
C = 2*pi*12
C = 2*12*pi
C = 24pi
This is approximately equal to 75.36 when you use the approximation pi = 3.14

Answer:
270°
Step-by-step explanation:
In a circle graph, the total angle would be 360°. You already know how much of the circle graph is apple juice, so you can find the angle of apple juice out of the entire circle graph.
Angle of apple juice section = × 360°
= 270°
