Find the area of the irregular figure (use 3.14 for pi). Show your work. Round to the nearest tenth.

Answer 1

13.7 ft^2

Explanation:

1. Find the radius of the semicircle by dividing the diameter by 2 to get 1.8

2. Find the area of the semicircle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 3.14(1.8^2)/2 = 5.0868

3. Find the area of the triangle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 1/2(3.6*4.8) = 8.64

4. Add both your numbers together to get 13.7268

5. Round to the nearest 10th to get 13.7 ft^2
