Answer: A cone with height 3 and radius 1 
Step-by-step explanation:
Hi, searching I found the image for the question, attached down below.
By rotating the triangle about line m, a cone with height 3 and radius 1 is produced.
Solid 3d objects are produced by rotating a 2d figure around a straight line that lies in the same place.
in our case, if we rotate the triangle around the line, the vertices in touch with the line m remains stationary, while the  remaining vertex follows the path of a circle, creating a cone.
 
        
                    
             
        
        
        
Answer:
You divide the circumference by 2 
Step-by-step explanation:
Divide the circumference by pi or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
 
        
                    
             
        
        
        
Answer: The answer is B, 6 1/2 
Step-by-step explanation:
6+5= 11
1/2+1/2= 1
11+1= 12
12-3=9
 
        
                    
             
        
        
        
Answer:
x = 3.5
Step-by-step explanation:
Triangle to the right:
4^2 + x^2 = 8^2
16 + x^2 = 64
y^2 = 48
Triangle to the left:
x^2 + 6^2 = 48
x^2 + 36 = 48
x^2 = 12
x = sqrt(12)
x = 3.5
 
        
             
        
        
        
Answer:
7 P.M. 
Step-by-step explanation:
Time at which the walk was begun = 4 p.m. 
Finished after rotating the clock 90° i.e. = 3 hours
Thus,
The time at which the task finished = 4 p.m. + 3hours
= 7:00 PM
