What is the best approximation for the perimeter of a semicircle with a diameter of 64 meters?
use 3.14 to approximate pi.

100.48 m

164.48 m

200.96 m

264.96 m

 By definition, the perimeter of a semicircle is given by:
  
 Where,
 d: diameter of the semicircle
 r: radius of the semicircle.
 The radius of the semicircle is given by:
 
 Where,
 d: diameter of the semicircle
 Substituting values:
  
 Then, the perimeter is:
 
 
 The perimeter of the semicurcle is given by:
 P =  164.48 m
