The first thing you need to do is find the radius of the semicircle. To do that you look to see that the width of the rectangle is the same as the radius. Once you have the Area of a Semicircle calculated multiply it by 3. then, we know that the other length of the rectangle is 3 diameters of a semicircle this means that you multiply the radius of 7 by 6 which gives you 42. You take the area of the rectangle (294) and subtract the area of the 3 semicircles(230.79) Which gives you the answer of 63.21cm^2
2) Find the area of a parallelogram with a height of 8 inches and a base of 14 inches.
A=bh=14·8=112in²
3) Find the surface Area of the rectangular prism with a length of 15 cm, height of 7 cm, and width of 5 cm.
A=2(wl+hl+hw)=2·(5·15+7·15+7·5)=430cm²
4) Find the volume of the following figure:

5) You are wrapping a cube shape present that is 9 inches tall. How much wrapping paper will you need to wrap the entire present.
SA =
= 9x9x9 = 729in²
6) A truck has a trailer that has a length of 13ft, a width of 6ft, and a height of 8ft. What is the volume of the trailer?
