The solution is false!
3.1 would become a fraction that will be calculated back into a decimal by the 4th power making it 92.3521=3,600.. so the equality is false because the left hand and the right hand side are different.
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:5
Step-by-step explanation:
a2+b2=c2
a2+12squared=13 squared
169-144=a2
a2=25, now that we have 25 we have to find the square root which is 5.
It’s b i got that same question and got it right
Argument
Let the second angle = x
Let the first angle = 2x
Let the third angle = x + 64
Substitute and Solve
x + 2x + x + 64 = 180 Collect the like terms on the left.
4x + 64 = 180 Subtract 64 from both sides.
4x = 180 - 64
4x = 116 Divide by 4
x = 116 / 4
x = 29
Conclusion
x = 29
2x = 58
x + 64 = 93 I'm leaving you with the problem of checking this out.
Answer
The first angle = 58
The second angle = 29
The Third angle = 93
