Question

What is the approximate area of the shaded region of this figure?

Answer 1

15.5 square inches

Step-by-step explanation:

The shape has two circles each with a diameter of 6cm.

Radius of the circle = 6/2 = 3cm

The outer shape is a rectangle with dimensions:

Length = 12cm

Breadth = 6cm

Area of the shaded region = Area of the rectangle - 2(Area of the Circle)

`=(L* B)-2(\pi r^2)`

Substituting the given values, we have:

`\begin{gathered} =(12*6)-2(3.14*3^2) \\ =72-56.52 \\ \approx15.5\text{ square inches} \end{gathered}`

The approximate area of the shaded region of this figure is 15.5 square inches.
