Area ( If you know the circumference) :
C^2 / (4×3.14) Brackets are important! 
So you have to type :
53.38^2/(4×3.14) 
= 226.865
        
             
        
        
        
Answer:
5 1/3
Step-by-step explanation:
16/3 = 32/6
32/6 = 5 2/6 = 5 1/3
 
        
                    
             
        
        
        
I found the correct image that accompanies this problem and edited it with my answers.. Pls. see attachment. 
Based on the attachment, the correct statements are:
<span>1) DO,2 (x,y) = (2x, 2y)
2) Side Q'S' lies on a line with a slope of -1.
Q'(-6,6) S'(-2,2) 
m = y1 - y2 / x1 - x2
m = 6 - 2 / -6 - (-2)
m = 4 / -4
m = -1
</span><span>5) The distance from Q' to the origin is twice the distance from Q to the origin.

Answer:
Y = 50x
Step-by-step explanation:
Remember that slope intercept form is Y = mx + b indicating that m is the slope
To solve this equation use the formula
Y2 - y1 , x2 - x1: 
50 - (- 50) = 100
25 - (-25) = 50 
100/50 = 50/1
So the answer is y = 50x
 
        
             
        
        
        
Answer:
34.04 cm²
Step-by-step explanation:
Formula for a trapezoid:
a + b ÷ 2 × height
Substitute the values:
11.7 + 3.1 = 14.8
14.8 ÷ 2 = 7.4
7.4 × 4.6 = 34.04
The answer is 34.04 cm²
