Answer 1

Ответ: 40πсм²

Пошаговое объяснение:

S=2πRH=2π*2*10=40π/см²/

Answer 2

Calculation of the lateral surface area of a cylinder

To find the lateral surface area of a cylinder, we need to know the height and radius of the base. In this case, the height is given as 10 centimeters and the radius of the base is given as 2 centimeters.

The formula for the lateral surface area of a cylinder is:

Lateral Surface Area = 2 * π * radius * height

Substituting the given values into the formula, we get:

Lateral Surface Area = 2 * π * 2 cm * 10 cm

Calculating the result:

Lateral Surface Area = 40π cm²

Therefore, the lateral surface area of the given cylinder is 40π square centimeters.

Please note that the exact numerical value of π (pi) is approximately 3.14159.
