Answer:
153.86 [tex]m^{2}[/tex]
Step-by-step explanation:
Formula for the area of a circle is [tex]r^{2}\pi[/tex] where [tex]\pi[/tex] = 3.14 and [tex]r^{2}[/tex] is radius times radius, which in this case is 7 since radius is 1/2 diameter.
So 7 multiplied by 7 = 49 then 49 multiplied by 3.14 = 153.86 [tex]m^{2}[/tex]
