Answer: B is the correct option.
Step-by-step explanation:
Given the formula A=2 π r^2 + 2 π rh.
Where radius is 3x - 2 cm and height is
x + 3 cm
Find r^2= (3x -2) (3x -2) = 9x^2 + 4
rh = (3x -2) (x + 3)= 3x^2 + 7x - 6
Slot the values into the formula
A = 2 π (9x^2 + 4) + 2 π (3x^2 + 7x - 6)
Combine the values by adding like terms.
A = 2 π ( 9x^2 + 3x^2 + 7x + 4 - 6)
A = 2 π ( 12x ^2 + 7x - 2), i hope this helps, please mark as brainliest answer.
