Hey there, Guest!

Random question, this is from 8th-grade math ALEKS, right?

First, we need to find the area of the rectangle and then subtract the area of the circle from it.

1) $35*19=630$

2) $A=(3.14)r^2$

 $A=3.14*81$

$A=254.34$

3) 630-254.34

=$375.66 cm^2$

And there you have it, 375.66 cm^2 is your answer, mate. ;)

Hope this helped! :)
