Here is the solution:

----------------------------------------

Find the volume of the cylinder:

Volume of cylinder = πr²h

Volume = π(3)²(5)  = 45π cm³

Find the volume of the conical hole:

Volume = 1/3 πr²h

Volume = 1/3 π (3/2)²(8/9) = 2/3 π cm³

Find the volume of Metal A:

45π - 2/3π = 133/3 π

Find the ratio: A : B

A: B  = 133/3 π : 2/3 π

Multiply by 3:

A: B  = 133 π : 2 π

Divide by π:

A: B  = 133 : 2

Answer: The ratio is 133 : 2
