A community group is building a playground on a rectangular lot of land. The lot measures 6x by 9x and they want to cut out an area for a circular jungle gym with a radius of 4x. How much of the land will be left over after the jungle gym is built? (1 point)

Answer 1

area of lot = (6x)(9x) = 54x^2
area of circle = π(4x)^2 = 16πx^2

amount left over = 54x^2 - 16πx^2
= (54-16π)x^2
