Answer:
[tex]4298.66mm^{2}[/tex], or [tex]1369mm^{2}[/tex][tex]\pi[/tex]
Step-by-step explanation:
Use the formula for area of a circle
A = [tex]\pi[/tex][tex]r^{2}[/tex]
the radius is half the diameter, so divide 74 by 2 then substitute it as r
A = [tex]\pi 37mm^{2}[/tex]
multiply 37 by 37
A = [tex]1369mm^{2} \pi[/tex]
multiple 1369 by pi(3.14)
[tex]1369mm^{2} \pi[/tex] or [tex]4298.66mm^{2}[/tex]
