A storage drum in the shape of a cylinder is 3 feet tall and has a diameter of 4 feet. What is the total surface area of the storage drum? Use 3.14 for Pi and round the answer to the nearest tenth. Recall the formula S A = 2 pi r squared + 2 pi r h. 20.0 37.7 50.2 62.8

THIS IS THE BEST ANSWER 👇

Step by step explanation:

Step 1: Find the surface area

Radius = Diameter / 2

Ga = 4/2

Ga = 2

Surface Area = 2 pi * r * h +2 pi * r ^ 2

Surface Area = 2 pi * (2) * (3) + 2 pi * (2) ^ 2

Surface Area = 2 pi * 6 + 2 pi * 4

Surface Area = 12 pi + 8 pi

Surface Area = 20 pi

Surface Area = 62.8 ...

Option D, 62.8
