Answer:
8. [tex]25\pi[/tex] [tex]in^2[/tex]
11. [tex]9\pi[/tex] [tex]m^2[/tex]
Step-by-step explanation:
Area = [tex]\pi r^2[/tex]
r = d/2
[tex]\pi[/tex] = 3.14
8.
r = 10/2
r = 5 in
Area = [tex]\pi 5^2[/tex]
Area = [tex]25\pi[/tex] [tex]in^2[/tex]
10.
r = 6/2
r = 3 m
Area =[tex]\pi 3^2[/tex]
Area = [tex]9\pi[/tex] [tex]m^2[/tex]
Hope it helps! (:
