The height of the cylinder is 15 cm, and the radius of its base is 4 cm. Find the perimeter of the rectangle ABCD that forms the side of the cylinder.
The side of a cylinder is a rectangle in which one side is the height, and the other is the circumference of the base of this cylinder.
Find the circumference by the formula: с = 2πr,
s = 2 * 3.14 * 4 = 25.12 cm.
We find the perimeter, this is the sum of the lengths of all sides, that is: 2 * 15 + 2 * 25.12 = 80.24 cm.
Answer: The perimeter of the rectangle ABCD is 80.24 cm.
