Use 3.14 for π.

Enter your answer, as a decimal, in the box.

Thank you for your response! I personally do not think I can, and I would think I would have to have this explained to me to some extent. It's not that I fell asleep in class or anything, I just didn't get this part so much and want to get a passing grade on test!

The semi circle area is 1/2 of a circle of radius 2   (the diameter is 4 from the graph)

    area of the full circle would be  pi r^2         

     semi circle area = 1/2 pi r^2 = 1/2 pi (2^2)

 

Area for a triangle is 1/2 bh     b= 4   h= 5   (from the graph)

       triangle area =  1/2 (4)(5)

 

Add the reds together for the final answer ....wooohooooo!
