Answer:
Diameter is the width = 7.64 ft
Step-by-step explanation:
Perimeter would need to be the arc of a semi circle measuring less than or equal to 12 Where perimeter therefore = 12* 2 = 24 24 / 3.14 = 7.64331210191 where 3.14 the value for pi and formula of a semi circle we use radius = 1/2 pi * 3.82 ^2 = D * pi = 7.65 and radius =7.64 / 2 = 3.82 so answer is the diameter = 7.64 ft
