Answer:
2411.52 cm³
Step-by-step explanation:
V = (2/3)πr³        Use the equation for volume of a hemisphere
V = (2/3)(3.14)(8)³     Simplify the exponent
V = (2/3)(3.14)(512)   Multiply
V = 1071.79 cm³
V = πr² h/3                   Now find the volume of the cone
V = (3.14)(8)²(20/3)      Simplify the exponent
V = (3.14)(64)(20/3)      Multiply
V = 1339.73 cm³
Add both of the volumes together to get the volume of the figure.
1071.79 + 1339.73 = 2411.52 cm³

So the easiest way to solve this is to use the straight line provided .
180=90+61+x
180=151+x
29=x
        
                    
             
        
        
        
we know that
The area of the hexagon is equal to the sum of the areas of the six equilateral triangles
Let
x-------> area of one equilateral triangle
so

Divide by  both sides
 both sides
 -------> area of one equilateral triangle
 -------> area of one equilateral triangle
To find an equivalent expression for the area of the hexagon based on the area of a triangle, multiply the area of one equilateral triangle by 
 
 
therefore
the answer is
The equivalent expression is equal to
