Answer:

See below

Step-by-step explanation:

1.  C = 2(3.14) for r

   r = C / 3.28

2.  A = 1/2 b h  for b

    b = A2 / h

3.  y = Mx + b for x

    y - b = Mx

    x = (y - b) / M

4.  A = 1/2 (a + b) h for  h

    A = (1/2a + 1/2b)h

    A = 1/2ah + 1/2bh

    A = (a + b) h / 2

    h = 2A / (a + b)

5.  V = (3.14) r² h  for h

   h = V / (3.14 r²)
