What is the approximate area of the shaded region in square inches? use π = 3.14.

Hence the area of shaded region is 25.12 square inches.

Step-by-step explanation:

We are asked to find the area of the shaded region i.e. we need to find the area of the annulus region.

The radius of the inner circle(r) is inch.

and that of the outer circle(R) is inch.

since the diameter of the outer circle is 9 inch and hence its radius is inch.

similarly the radius of inner circle is: radius of outer circle-1 inch.

Hence the area of the shaded region is given by:

Area of the outer circle-Area of inner circle

Area of outer circle=

and Area of inner circle=  

Hence the area of shaded region=

Hence the area of shaded region is 25.12 square inches.
