Step-by-step explanation:
Answer:
V = 38659.68 cm^3
Step-by-step explanation:
If we pretend A barrel is a cylinder we use V=πr^2h for the volume. We know h, but we need to find r
The question tells us the circumference, well how do we find circumference? C = 2πr, so we can use this to find r.
C = 2πr
56.52 = 2 * 3.14 * r Here divide both sides by 2*3.14
56.52/(2*3.14) = r
9 cm = r
Now we can just plug into the volume.
V=πr^2h
V = 3.14 * 9^2 * 152
V = 38659.68 cm^3
I feel I should mention this is all true if the circumference is in centimeters, since the question didn't specify.
Store A:
sells fabric for $ 3.00 per yard:
c (t) = 3t
The domain restrictions for this case are:
numbers greater than or equal to zero
Equivalently:
t that belongs to [0, infinity)
Store B:
sells packages of fabric for $ 3.00 each:
c (t) = 3t
The domain restrictions for this case are:
numbers greater than or equal to zero: [0, infinity)
integer values only: (1,2,4...n)
