Answer:
236 cubic units (to 3 significant figures)
Step-by-step explanation:
volume of a cylinder =  r²h   (where r = radius and h = height)
r²h   (where r = radius and h = height)
Therefore, volume =  x 5² x 3
 x 5² x 3 
                                =  x 25 x 3
 x 25 x 3 
                                = 75 
 
                                = 236 cubic units (to 3 significant figures)
 
        
             
        
        
        
x^2*(-3x)=-3x^3. The power of x becomes 3 because you add the powers of x. (2+1=3)

Answer:
(7y + 3x)(7y - 3x)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
49y² - 9x² = (7y)² - (3x)²                   {a = 7y ; b - 3x}
                = (7y + 3x)(7y - 3x)
