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
Answer:
Noelle has four times as many apples in her grocery bag as her friends
Dakota and Kylie combined. Dakota has 1 apple in her bag. Noelle has 16
apples in her bag. How many apples does Kylie have in her grocery bag?
