Answer:
5/V2=2.5×V2
Step-by-step explanation:
This is an isoscelle right triangle:
x²+x²=5²
2x²=5²
x=5/V2=5×V2/2=2.5×V2
where V2=sqrt(2)
 
        
             
        
        
        
Answer:
83.79 cm² 
Step-by-step explanation:
(please refer to attached)
recall that the volume of a cone is given by 
V = (1/3) π r² h
where
r = radius = given as 4 cm
h = height = given as 5 cm 
assume π = 3.142
substituting the values into the formula:
V = (1/3) π r² h
V = (1/3) (3.14) (4)² (5)
V = 83.79 cm² 
 
        
             
        
        
        
The slope is the change in Y over the change in X.
 Use the two blue dots on the graph :
(-1,0) ans (3,4)
Slope = (4 - 0) / (3 - -1)
= 4 / 4
= 1
