Answer:
439.6 cm²
Step-by-step explanation:
Surface area of the cylinder is the length of the rectangular strip that goes around, and the are of the two circles
Area circle = πr²
Area circle = 3.14 * 7²
Area circle = 3.14 * 49
Area circle = 153.86
The area of both circles is 153.86 x 2 = 307.72
The rectangular strip is the diameter by the height
Diameter = 2πr
Diameter = 14*3.14 = 43.96
The strip is 43.96 x 3 = 131.88
Total surface area is 307.72 + 131.88 = 439.6
