The answer is around 168.56
work :
the side of the square is 28 in
so the diameter of the circle is 28 in, too(look at the picture)
then the radius is 14 (28/2)
the area of the circle is

the area of the square is

so the area of the shaded region will be around:

good luck
The difference between the masses is
4.55·10¹³ kg -1.78·10¹² kg
= 4.55·10¹³ kg - 0.178·10¹³ kg
= (4.55 -0.178)·10¹³ kg
= 4.372·10¹³ kg
Rounded to the appropriate precision, the mass of the Antarctic iceberg exceeds that of the Rock of Gibraltar by ...
4.37·10¹³ kg
-53/200 is what your fraction will be simplified to
4128 divided by 50. The answer is the number of bags
