A family is building a circular fountain in the backyard the yard is rectangular and measures 6x by 7x and the fountain is going to be circular with a radius of 2x once the fountain is built what will be the area of the remaining yard?

Answer 1

Ac + Ar = Ay, pi*r^2 + Ar = 6x*7x, 3.14*(2x)^2 + Ar = 42x^2,
12.57x^2 + Ar = 42x^2,
Ar = 29.4x^2 = Area remaining.

Answer 2
