Answer:

415.96yds sq

Step-by-step explanation:

ok so you have two squares, three rectangles, two semicircles, and half the SA of a cylinder.

SA of the squares=(8*8)*2=128

SA of the rectangles=(10*8)*3=240

SA of the semicircles= 3.14*r*r=3.14*4*4=3.14*16=50.24

SA of half the cylinder= (2*3.14*r*h)/2= (2*3.14*4*10)/2=(3.14*80)/2=251.2/2=125.6

Now you add them all together

128+240+50.24+125.6=415.96

and you add units

415.96yds sq
