Answer:


4298.66mm^(2), or
1369mm^(2)
\pi

Explanation:

Use the formula for area of a circle

A =
\pi
r^(2)

the radius is half the diameter, so divide 74 by 2 then substitute it as r

A =
\pi 37mm^(2)

multiply 37 by 37

A =
1369mm^(2) \pi

multiple 1369 by pi(3.14)


1369mm^(2) \pi or
4298.66mm^(2)
