Answer:
Step-by-step explanation:
The volume of a cylinder is:
where 
is the radius and 
is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is 
thus:
Dividing everything between pi:
We can see that the solution for this is 
since 
We have the radius, now we find the height:
Answer:
13 and 8
Step-by-step explanation:
height is not used to find the bottom triangle
<span>Julia is X+5
</span><span>x+x+5=31

Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
So 3^X= 2 is an exponential equation. The inverse of an exponential in ln. so take ln of both sides to solve.
Another way is to change the exponential into a log equation
So that would be log with base 3 to the power of 2 equals x.
