Question

a circular shapes area can be found with the formula $a = \pi r^{2}$, where $r$ is the. a shape is one that combines two or more simple shapes into a single figure.

Explanation:

For the first blank, in the formula \(A = \pi r^{2}\) for the area of a circle, \(r\) represents the radius. For the second blank, a composite shape is defined as one that combines two or more simple shapes into a single figure.
