Find the perimeter (or circumference) and area of the figure.Give the exact value and an approximation using ? ? 3.14.
A. circumference = 5.5? ? 34.54 ft
area = 121? ? 379.94 sq ft
B. circumference = 5.5? ? 34.54 ft
area = 30.25? ? 94.99 sq ft
C. circumference = 11? ? 34.54 ft
area = 121? ? 69.08 sq ft
D. circumference = 11? ? 34.54 ft
area = 30.25? ? 94.99 sq ft
