Question

find the perimeter of semicircle whose radius is 16.1 cm .​

Answer 1

Answer:

As we know,

Perimeter of circle= circumference= 2 * Pie* r.

Therefore perimeter of semicircle=half of circumference of circle.

                                                        =1/2*2*Pie*r

                                                         =Pie *r

                                                         =(3.14*16.1) cm

                                                          =50.554 cm
