Find the area of the lateral surface of the cylinder if its radius is 15 cm and its height is 30 cm.
| January 1, 2021 | education
A cylinder is a geometric body formed by rotating a rectangle around its side.
The lateral surface area of the cylinder is equal to the product of the circumference of the base of the cylinder by the height. Since the length of the base of the cylinder is equal to the product of the doubled radius and the PI number, the formula for the lateral surface can be produced as follows:
Sb.p. = 2 π r h;
Sb.p. = 2 · 3.14 · 15 · 30 = 2826 cm2.
Answer: the total surface area of this cylinder is 2826 cm2.
