The area of a 2D form is the amount of space within its perimeter. The plastic that would be needed to cover the paper towel roll is 263.76 in².
What is an area?
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The plastic that would be needed to cover the paper towel roll is equal to the surface area of the paper towel roll, therefore, the surface area is,
Total surface area = (2πrl) + 2(πr²)
= (2×π×3×11) + 2(π×3×3)
= 66π + 18π
= 263. 76 in²
Hence, The plastic that would be needed to cover the paper towel roll is 263.76 in².
