Answer:
12
Step-by-step explanation:
Volume of cylinder is pi*r^2*h (this is equal to 540pi in this case)
So we have 540pi=pi*r^2*h
this means that 540=r^2*h (I just divided both sides by pi since both sides were being multiplied by pi)
The height,h, is 15 so plug in 540=r^2*15
Divide both sides by 15 giving 540/15=r^2
So r^2=36
So r=6
The diameter,d, is twice the radius, r.
So d=2(6)=12
-3/2 = x + c
x = - [(3/2) + c]

Answer:
The artist used 
more of silver wire
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
we know that
The Perimeter of the square is equal to
where
a is the length side of the square
so
so
Each side of the square has a length of 10 in
step 2
Find the circumference of the circle
The diameter of the circle is equal to the length of the side of the square
The circumference is equal to
we have
substitute
step 3
Find the difference
