Answer:
81.0
Step-by-step explanation:
The tenth is the decimal directly to the right of  the period (.) Since the next number to the right is 1, you would round down, which is 0.
 
        
                    
             
        
        
        
Answer:
The area of the circle is 28.26
The area of the circle in terms of pi is 9π
Step-by-step explanation:
radius = half of diameter
d = 6
r = 6/2 = 3
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 3
π = pi
a = π * r²
we replace with the known values
a = π * (3)²
a = π * 9
a = 9π 
The area of the circle in terms of pi is 9π 
9 * 3.14 = 28.26
The area of the circle is 28.26

Solving for "K" , got it! :) 
I'll make it easier to solve 
(k)4+3-14=?
? = 0
4(k)-11 = 0 
Take off the '0' and the addition symbol so we can add from 11 on your sides
4(k) - 11
+11   +11
---- ----
15k. 22 
      ⬆ This would be your answer for k            
 4(k) = 11
÷4 ÷4 
--- ----
1K ?
K = 11/4 (for fraction) 
K = 2.75 (as a decimal)
