A family is building a circular fountain in the backyard. the yard is rectangular and measures 10x by 15x and the fountain is going to be circular with a radius of 4x. Once the fountain is built, what will be the area of the remaining yard?

A. 2x^2(75-8Π)
B.150x^2-4Πx^2)
C.134Πx^2
D.134x^2
My answer is A

Please correct me if I'm wrong.

Im basically suppose to
Find the area of the rectangle.
Find the area of the circle.
Subtract the area of the circle from the area of the rectangle.

I'm guessing D
The answer should be D..... because for finding out the remainig area you'll have to minus the area of circle from area of rectangle i.e ((10x)×(15x)) minus (pi×(4x)^2)
This will give you D.
D is wrong. It is not B, nor C. Duh.

15x*10x-PI*(4x)^2
2x^2(75-8PI)
what is it\
its A
The only reason I dissed you in the first place is because you denied seeing me... Now I'm pissed off. ;)
