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)
