The lateral surface area of the cylinder is 144 cm 2. Find the axial section area of the cylinder.
| February 10, 2021 | education
In order to find the area of the axial section of a cylinder, it is necessary to multiply the diameter of its base by the height.
Since the base diameter is equal to two radii, the formula for the axial section area looks like this:
S = 2rh.
The lateral surface of the cylinder is 144 cm2.
The lateral surface area of the cylinder is calculated by the formula:
Sb.p. = 2πrh.
Based on this, we can find the axial section area. For this you need:
S = 2πrh / π;
S = 144 / 3.14 ≈ 45.9 cm2.
Answer: the axial section area is 45.9 cm2.
