Answer:
exact area = 25(pi) m^2
approximate area = 78.54 m^2
Step-by-step explanation:
diameter = 10 m
radius = diameter/2 = 10 m / 2 = 5 m
area = (pi)r^2
area = (pi)(5 m)^2
area = 25(pi) m^2
area = 78.54 m^2
 
        
             
        
        
        
Answer:
6.21 times more
Step-by-step explanation:
Assuming 2.04 x 10^11 was only a typo
you would need to first equal the powers of 10
so 20.4 x 10^10 and 3.28 x 10^10
now that they have the same powers

if it's asking for how many times i would approximate it to 6.21 times more
 
        
             
        
        
        
Pretty sure it's 0, if you mean 2 to the power of 0
