Area of semicircle = 1/2 the area of a circle:

radius is half the diameter of 6ft.

Area of the rectangle:

Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.

Answer:
x=12, DO=45O, G=45, DG=90
Step-by-step explanation:
Mid point means both lenghts are equal
4x-3=2x+21
2x=24
X=12
-----------------
1)4(12)-3=48-3=45
2)2(12)+21=24+21=45
-----------------------------
DO=45
OG=45
DG=90
 
        
                    
             
        
        
        
Answer:
   
Step-by-step explanation:
The distance (d) between two points in 3 dimensions is ...
   d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)
Then the distance between (a, -b, -4) and (0, 0, 0) is ...
   d = √((a -0)² +(-b -0)² +(-4 -0)²)
   = √(a² +b² +16)
