Question

A circular flower garden surrounds a sculpture on a square base as shown.

What is an expression for the area of the flower garden?

Answer 1

well, let's first off get the whole area of the circular garden, and then from it subtract the area of the squarish sculpture, thus what's leftover is simply the shaded area, or just the garden minus the sculpture.

`\stackrel{\textit{\LARGE Areas}}{\stackrel{whole~circle}{\pi (6x)^2}~~ - ~~\stackrel{square}{(4x)(6x)}}\implies 36\pi x^2-24x^2\implies {\Large \begin{array}{llll} 12x^2(3\pi -2) \end{array}}`
