The radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
 
We have:
Length of the arc of a circle:
s = 7.34 units
The measure of central angle:
θ = 81 degrees =  1.413 radians
s = rθ
r is the radius of the circle
7.34 = r(1.413)
r = 5.19 ≈ 5.2 units
Thus, the radius of the circle is 5.2 units if the length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81°

Answer:
48
Step-by-step explanation:
8*8 = 64 (big square)
4*4 = 16 (shaded square)
64 - 16 = 48
 
        
             
        
        
        
Answer:
y = 10x  + 100 
Step-by-step explanation:
Given the information: 
She earns the same  amount per hour as she did in her old job $ 100 sign-on bonus 
=> the equation for line p in the form y= mx  where: 
- x is the number of hour she worked 
=>  the equation for line q in the form y= mx + 100 ($ 100 sign-on bonus ) 
From that, we see that the two equations have the same slope or you can use a transformation to map line p onto line q 
We can create two points (0, 0) and (2, 20) are on line p  
<=> m =  
 
The equation for line p is y = 10x 
=>The equation for line q should include the hourly earnings at the
new job plus the sign-on bonus. The equation is y = 10x  + 100 
Hope it will find you well.
