Question

Write The Formula For Perimeter Of Semicircle

Answer 1

Answer:

2πr/2+(length of diameter)=πr+(length of diameter)

Answer 2

Perimeter of Semi-circle = 1/2 of circumference of circle + diameter

Perimeter of semi-circle = 1/2 × 2πr + 2r

Perimeter of semi-circle = πr + 2r

Perimeter of Semi-circle = r ( π + 2 )

Hence, Perimeter of semi-circle is r ( π + 2 )

Where, r is the radius of circle.
