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.
Answer: 56
Step-by-step explanation: Divide 42 by 3 and then multiply by 4
Answer:
Okay the answer is 6/8
Step-by-step explanation:
1/4 is equal to 2/8 so take 3/4 and simplify to 8s which is 6/8.
<span>Conditional probability of b given a is given by dividing Probability of event b with the probability of both a and b occurring together. Hence in this case, conditional probability of b given a is 0.1 divided by 0.6. On division, the result that is obtained is 0.16.</span>
Answer: x^2+10x+5x+50 = x^2+15x+50
Step-by-step explanation:
Basically, use something called FOIL. It stands for first, outer, inner, last. Basically multiply the first x, by the first x in the second parenthesis. Then multiply that x by the outer x in the second parenthesis. After that, multiply the 5 by the inner x. Then the five by the ten.
