The cylinder diameter is 2 cm, and the diagonal of the axial section forms an angle of 60 ° with the base diameter. calculated the total surface area and volume of the cylinder.
In order to calculate the total surface of a cylinder, you need to find the height and radius of the base.
Since the total surface consists of the sum of the lateral surface and two base areas, we first find two base areas.
Since the diameter is 2 cm, the radius is 2/1 = 1 cm, and the two areas are 2 * 3.14 cm2.
Find the height of the cylinder, which is: 2√3 cm, then the side surface is 2 * 3.14 * 2√3 * 1.
Therefore, the total surface is: 2 * 3.14 + 2 * 3.14 * 2√3 * 1 = 28 cm2.
