Find the volume of the body obtained by rotating a rectangle with sides of 5 cm

Find the volume of the body obtained by rotating a rectangle with sides of 5 cm and 8 cm passing through the midpoints of its smaller sides.

The result of the rotation specified in the problem statement is a cylinder.
Cylinder parameters:
Base radius r = 5/2 = 2.5 (cm).
Cylinder height h = 8 (cm).
To find the volume of a cylinder, use the formula:
V = S * h = π * r² * h = 3.14 * 6.25 * 8 = 157 (cm³).
Answer: the volume of the resulting body (cylinder) is 157 cm³.
