Divide the figure into smaller, known, and solvable figures

Step-by-step explanation:

A composite figure is a figure that is composed of multiple shapes, such as circles, polygons, triangles, etc. The area of the smaller figures that the overall figure is made up of can be solved using known equation, such as a the rectangle of a rectangle can be found by multiplying the length by the width of the rectangle. The overall composite figure lacks a general equation that can be used to find the overall area of the figure, so it needs to first be divided into shapes of solvable areas, such as circles and polygons, each of which have an area that can be solved for easily. The areas of each of these can then be added together to find the area of the overall composite figure.

C

Step-by-step explanation:

3/4 * 4pi = 3pi

3pi + 4 =. 13

♡ The Answer(s) ♡

-1 (A) --> N/A!

-1 (B) --> N/A!

-2 (A) --> 1,156 Sq Meters

-3 (A) --> 40π Sq Meters

-3 (B) --> 125.6 m^2

♡ The Explanation(s)/Step-By-Step(s) ♡

-1 (A) --> N/A!

-1 (B) --> N/A!

-2 (A) --> We can figure out that the rectangle is 50 cm, and the triangle is 26 cm! In order to figure out the circle's cm, we can use the formula π x r^2. The radius of the circle is 10 cm, and the π is 3.14. We can multiply 3.14 by 10, this makes the number 31.4 cm! If we add the numbers, we end up with the sum of 107.4 cm. Converting 107.4 in Sq Meters leaves us with 1,156 Sq Meters! Therefore, 1,156 Sq Meters is your answer!

-3 (A) --> 125.6 m^2 is equal to 40π Sq Meters, This helps determine the exact area.

-3 (B) --> The approximate area of the sidewalk is 125.6 m^2. To solve this, you need to subtract the area of the inner edge of the lion pen from the outer edge of the lion pen.

A = π ( (11 m)^2 - (9 m)^2 )

A= π ( 121 m^2 - 81 m^2 )

A = π ( 40 m^2 )

A= 40π m^2. The area of the sidewalk comes out as 40π square meters, this is equal to 125.6 m^2, therefore, your answer will be 125.6 m^2.
