Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality
follows that A lies on the line.
B: x=3, y=13, then from the equality
follows that B lies on the line.
C: x=8, y=2, then from the inequality
follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality
follows that D lies on the line.
We need the radius to find the surface area. Since we have the circumference we can use that to find the radius.
C = 2πr
23 = 2(3.14)r
23 = 6.28r
23/6.28 = r
3.66 = r
Now use the radius to find the surface area.
SA = 4πr²
SA = 4(3.14)(3.66)²
SA = 168.33
Surface area is C. 168 cm²
Hope this helps :)
Answer:
COULD BE Y=6x-8
Step-by-step explanation:
The volume of each of The buckets is:
V1 = pi * r ^ 2 * h
Where,
r: radio
h: height
Substituting values we have:
V1 = 3.14 * (5/12) ^ 2 * (25/12)
V1 = 1.14 feet ^ 3
The volume of the warehouse is:
V2 = (100) * (50) * (20)
V2 = 100000 feet ^ 3
Then, the number of buckets of rocks she could store in a warehouse is:
N = (V2) / (V1)
N = 100000 / 1.14
N = 87719
Answer:
the number of buckets of rocks she could store in a warehouse is:
N = 87719
