Answer:establishment of diasporic merchant communities
Explanation:
All others are wrong
So use half the surface area formula: SA=2πr^2 and plug in what you already know
since you don't know the radius yet, solve for it using the circumference
C=2πr
514.96=3.14(2)r
82=r
SA=2π(82)^2
SA=6.28(6724)
SA=42,226.72
so your answer is 42,226.72 yards squared
Answer:
79 1/6 m
Explanation:
Perimeter of a rectangle = 2(length + width)
Length = 73/3 ; width = 61/4
Therefore.
Perimeter = 2(73/3 + 61/4)
Perimeter = 2(292 + 183) / 12
Perimeter = 2(475/12)
Perimeter = 950/12
Perimeter = 79 2/12
Perimeter = 79 1/6 m
