Perimeter: You have to add up ALL the sides 12+12+3+3= 30 in square is the Perimeter
Area: Multiply l*w A=l*w, so 12*3= 36 36 in. square is your Area
Substituting for r and h:-
volume = pi (x - 3)^2 * (2x + 7)
= pi* (2x + 7)(x^2 - 6x + 9)
= pi * (2x^3 - 12x^2 + 18x + 7x^2 - 42x + 63)
= (2x^3 - 5x^2 - 24x + 63) pi answer
