Answer 2

Answer:

The answer in 2 decimal places is 335.01 square inches

Step-by-step explanation:

From the problem, the figure has 3 circles inside the rectangle.

The shaded area is the area of the rectangle minus the areas of the 3 circles.

The rectangle has a dimension of 18 in by 30 in.

The circles have radii of 6 in, 9 in and 12 in.

Calculate the areas :

For rectangle :

A=l x w

A=30 x 18=540$in^{2}$

For Circles :

$A=\frac{\pi D^{2} }{4}$
