Surface Area of the cylinder is 6x² + 83x - 58 cm²
Step-by-step explanation:
- Step 1: Given surface area of the cylinder, A = 23r + 2rh. Here, r = (3x - 2) and h = (x + 3)
⇒ A = 23(3x - 2) + 2(3x - 2)(x + 3)
⇒ A = 69x - 46 + (6x² + 18x - 4x - 12)
⇒ A = 6x² + 83x - 58 cm²
The answer should be 7.5 mins, but I may have calculated wrong :/ I hope that helps you come closer in your answer :)
