Given a 30 meter x 60 meter garden with a circular fountain with a 5 meter radius, calculate the area of the portion of the garden not occupied by the fountain.

30 x 60 = 1800
3.14 x 25 = 78.25/2=39.125

1800 - 39.125 = 1,760.875 but this is incorrect

The answer choices are:
A. 1721 sq.m
B. 1879 sq.m
C. 2585 sq.m
D. 1015 sq.m

What am I doing wrong?

Thank you!
