Answer:
Scott is wrong because he did not add the diameter that connects the arc
the fence is 41.12 feet. He would buy 42 feet
Step-by-step explanation:
Circumference of a semicircle = πr + d
π = pi = 3.14
d = diameter = 16
r = radius = 16/2 = 8
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
( 3.14 x 8) + 16 = 41.12 feet
