Answer:


P = 8\pi

Explanation:

To solve this problem, we must calculate the circumference of one circle and multiply it by two because there are 2 circles (4 halves), that make up the perimeter.

We know the diameter is 4m, thus, the circumference of one circle (two halves) is:


C_1 = \pi d\\C_1 = \pi 4

To get the total perimeter (circumference) multiply the result by 2:


C = C * 2\\C = 4\pi * 2\\C = 8\pi
