Answer 1

Answer:

(2r+πr) is the formula for the Perimeter of a Semicircle

Step-by-step explanation:

Perimeter of semicircle = diameter + half of circumference

                                       =2r + 2πr/2 (diameter=2r and circumference= 2πr)  Perimeter of semicircle  = (2r+πr)

It can also be written as  r(2+π)
