Answer:
3^-5 or 1/3^5(b)
Step-by-step explanation:
3⁴•3^-9
When bases are same powers are to be added
So the above expression becomes
3^4+(-9)
3^4-9
3^-5

A squared plus B squared equals C squared, so what you need to do it square 5 and 7.
5 = 25
7 = 48
Then add then and square root your answer. 48 + 25 = 73. 73 square rooted equals an rounded amount of 8.6. SO the answer is D
        
             
        
        
        
Answer:
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h    where r is the radius and h is the height. 
We are given r = 5 and h = 2.5, plug those values in and simplify...
V = π(5²)(2.5)
        V = π(25)(2.5)
               V = 62.5π
