HERE'S HOW TO DO IT :)
A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles.
<u>To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.</u>
<u>(SEE EXAMPLE ATTACHED)</u>

<u>HERES WHAT WE KNOW ABOUT COMPOSITE FIGURES:</u>
<u>Composite Figures. A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). For example, figure ABCD is a composite figure as it consists of two basic figures</u>

Please note that pi has just one value. The only difference stems from round-off error when you don't use all of the digits following "3.14159 ... " to represent the value of pi. The formula for circumference is C = 2 pi r, or C = pi d,
where r=radius and d=diameter.
Circle A: Diameter 9 inches and Circumference of 28.26 inches
If the diameter is 9 inches, then C = 28.26 inches = pi (9 inches). Divide 28.26 inches by 9 inches. Note that you MUST round off the ratio (pi) that you obtain, since 28.26 has 4 significant figures and 9 has just one.
28.26
------- = 3.14, but because 9 has just one significant figure, you must round
9 this 3.14 to just 3.
You are a right triangle. You can tell this by both the 3 sides and the 90 degree angle.
Each pallet of cement weighs 303.5 pounds. You just have to divide 4,856 by 16
