Step-by-step explanation:
1/3 πr²h
Given 
diameter (d) = 8ft
radius (r) = d/2 = 8/2 = 4 ft
height (h) = 3 ft
Volume of cone



=50.24 ft³

For question 1:
Part i) 
2.6 x 2.6 = 6.76 cm squared
No unit conversions needed
Part ii) 
1.2 dm = 1.2 / 1000000 = 0.0000012 cm
0.0000012 x 0.0000012 = 0.00000000000144 cm squared
Question 2:
16.5dm = 16.5/ 1000 = 0.0165 m
0.0165 x 0.0165 = 0.00027225 m squared
I hope this has helped
        
                    
             
        
        
        
You need to multiply 188 by 25%. But first convert 25% to a decimal 0.25.
188*0.25 is 47
Now we subtract 188 - 47
Which is 141
$141 is the sales price.
        
                    
             
        
        
        
It would be 115,000. You round down since 16 is closer to 115,000 than 116,000.
