Find the area and the circumference of a circle with diameter 5 ft .
Use the value 3.14 for π , and do not round your answers. Be sure to include the correct units in your answers.
Area = 78.5 ft^2
Circumference = 15.7 ft
Wrong again!
r = 2.5
A = π(2.5)^2 = 19.63 ft^2
C = 2π r = 10π = 31.42 ft
How could the question ask not to round when π is involved ??
