Answer:
Total area, including top and bottom: 67.7 ft²
Explanation:
The area of the sides (only) is A = (circumference of base)(height of cylinder), and in this case A = 2(3 ft)(3.14), or
approximately A = 18.8 ft²
If you also want the areas of the base and top of the cylinder, perform the indicated calculations:
A (top and bottom) = 2π(3 ft)² = 48.9 ft²
So that the total surface area is (48.9 + 18.8) ft², or 67.7 ft²
