Answer:
x=42.3m
Step-by-step explanation:
x/47=82.8/92
92x=3891.6= 42.3m is the distance
 
        
             
        
        
        
First find the area of the base, and multiply that by the height. That's the answer. 
Area of the base: pi * 3*3 = 3.14*9 = 28.26
Volume of the cylinder: 28.26*8 = 226.08 cubic units
        
                    
             
        
        
        
Answer:
   Rs 8500
Step-by-step explanation:
For a cost price of c, the marked price is ...
   marked = c +25%·c = 1.25c
After the 15% discount, the sale price will be ...
   s = marked -15%·marked = 0.85·marked = (0.85)(1.25c) = 1.0625c
The profit will be the difference between the sale price s and the cost c:
   p = s -c
   500 = (1.0625c) -c = 0.0625c
Then the cost is ...
   500/0.0625 = c = 8000
and the sale price is ...
   s = c +p = 8000 +500 = 8500 . . . rupees
The selling price will be Rs 8500.
 
        
             
        
        
        
Answer:
radius of the hemisphere = 9 cm approx
Step-by-step explanation:
Volume of hemisphere = 
1527.4 = 
 =
 = 
 =
 = 
 = 729
 = 729 
r = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
r = 9 cm approx.
