The diameter of the LP is 50 cm. Find the products the circumference of this LP.

To find out the circumference of the considered LP, we apply the formula: L = Π * dpl, where Π is a mathematical constant (according to the condition Π = 3.1); dpl is the diameter of the considered long-playing plate (dpl = 50 cm).

Let’s calculate: L = Π * dpl = 3.1 * 50 = 155 cm.

Answer: The circumference of the LP in question is 155 cm.
