If we want to get B by itself, we need to "undo" every operation being done to it. Those operations are (in order):
- Multiplication by A
- Addition with 3C
To undo these then, we'll need to:
And, since this is an equation, we'll need to do both of those to the right side as well to keep everything equal. Here we go:
AB + 3C - 3C = D - 3C (subtracting 3C)
AB/A = (D - 3C)/A (dividing by A)
B = (D - 3C)/A
And we're done! If you'd like to see it formatted a little nicer, here's this:
Answer:
The volume is 945.26
Step-by-step explanation:
The volume is 945.26 (this is only if this is a right cylinder)
volume of right cylinder formula = πr^2h
r = 4.5
We know that the circumference is 9.
circumference = 2πr
so, you would have to divide 9 by 2 to get the radius which is 4.5
h= 15 (already given)
then just plug it in!
π4.5^2(15)
π4.5^2 = 20.25π
20.25 x π = 63.6172512352
63.6172512352 x 15 ≈ 945.26
Answer:
0.04 or 4/100
Step-by-step explanation:
Think of a percentage as a very lazily written fraction. 4% = 4/100
Just convert the fraction to a decimal.
