Answer:
38.465m^2
Step-by-step explanation:
d = 7m
r = d/2
r = 7/2 = 3.5m
A = [tex]\pi[/tex]r^2
A = [tex]\pi[/tex](3.5^2)
A = 12.25[tex]\pi[/tex]m^2 or 12.25(3.14)m^2 = 38.465m^2
(Pi is not exactly 3.14 , it's a long decimal number that never ends which means pi is an irrational number)
Hope this helps.. (Correct me if I'm wrong)
