Answer:
615.75216....
Step-by-step explanation:
The formula is A = π * (ø/ 2)^2
A = Circle area
π = Pi = 3.14
ø = Circle diameter
A= 3.14  (28/2)^2
 
        
                    
             
        
        
        
Answer:
B: (2,[infinity]]
Step-by-step explanation:
because you will take all numbers bigger than 2 but 2 is not included
 
        
             
        
        
        
You can find the value of the hypotenuse if you apply the Pythagorean Theorem, which is show below:
 h²=a²+ b² ⇒ h=√(a² + b²)
 h: hypotenuse (the opposite side of the right angle and the longest side of the triangle).
 a and b: legs (the sides that form the right angle).
 Then, you have:
 h²=a² + b²
 h²=12²+12²
 h=√ ((12)² + (12)²)
 h=12√2
 What is the lenght of the hypotenuse?
 The answer is: The length of the hypotenuse is 12√2
 
        
             
        
        
        
The value of x can be found using the sine function.
sin 30 = x/8
8 (sin 30) = x
4 = x
        
             
        
        
        
Answer: yes it can be a measure of a triangle
I hoped i helped you and can i have brainliest if it's ok? ty
Sides: a = 6   b = 11   c = 13
Area: T = 32.863
Perimeter: p = 30
