The problem ask to calculate the integral of (f(2x)) dx from 0 to 2 a. Base on my calculation and further computation, I came with a solution that leads to an answer of (f(2x))dx = 5. I hope you are satisfied with my answer and feel free to ask for more if you have clarification and further question.
Answer:
1. 60 cm^2
2. 132.67 cm^2
3. 72.67 cm^2
Step-by-step explanation:
1. Area of rectangle
A = LW = 5 cm * 12 cm = 60 cm^2
2. Area of circle
A = (pi)r^2 = 3.14(6.5 cm)^2 = 132.67 cm^2
3. Area of shaded region
A = area of circle - area of rectangle
A = 132.7 cm^2 - 60 cm^2 = 72.67 cm^2
Since these are similar triangles you can use any two corresponding sides to figure out the scale factor.
Use the bottom side. Going from the first triangle to the second the scale factor is:
15/9 = 5/3
Do you know how to translate that in English
