This composite shape is a rectangle with a semicircle attached on one end. the diameter of the semicircle is 6 feet. what is the approximate area of this composite figure? use 3.14 for pi and round to the nearest whole number. 46 ft2 74ft2 88 ft2 117ft2

As we can see on the picture we have a rectangle and half of circle.

The areas for half circle and rectangle are:

The area of the figure is the sum of the area of half circle and rectangle. Also the height of a rectangle (6ft) is a diameter of a half circle therefore the radius of half circle is 6ft ÷ 2 = 3ft.

Now we calculate the areas.

The area of the figure is approximately 74ft squared.

Hope this helps.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
