ok
Volume of a cylinder = Area of the base x height
= pi*r^2 * h
= 3.14* 3.2^2*8
= 3.14*10.24*8
= 257.23 km^3
We got the same result, you just need to round to the nearest hundred.
pi = 3.14
r = 3.2 km
h = 8 km
To find the answer, divide.
2/3≈0.66666667
We know that 1/3 is .333333..., so .666666 is 2.3. To convert to a percent, we multiply by 100.
66.66666%
We can convert this .66666 back into 2/3.
66 2/3%
Therefore, our answer is
= 66 2/3%
I hope this helps!
2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:

Answer:
r = 9
