Answer:
The answer is 68°.
Step-by-step explanation:
Following the arc length equation:
s = r * θ where s is arc length, r is radius of the circle, and θ is the angle in radians.
12 is the Radius of the Circle and therefore solve for θ:
θ = 
= 
= 
rad. or radians
Now, convert the radians to degrees:
= 68°
The sum of y and 9

Answer: The mass of each passenger is 550 kg.
The mass of front decoration = 200 Kg.
Step-by-step explanation:
Let the mass of each passenger be 'x'.
Let the mass of front decoration be 'y'.
So, Number of passenger = 6
Mass of 6 passengers and front decoration = 3500 kg.
Number of passengers = 4
Mass of 4 passengers and front decoration = 2400 kg.
According to question, it becomes,
so, From Eq(1) and Eq(2), we have,
Hence, the mass of each passenger is 550 kg.
The mass of front decoration = 3500-550(6)=200 Kg.

Step-by-step explanation: six
<h3><em><u>Answers With Steps:</u></em></h3><h3>Question 1:</h3>
For the first problem, understand that you are solving for the area of a circle. The equation for the area of a circle is pi r². By using the leash length as the radius (r), you can get the answer. (The leash length is 3 meters long.)
<em>Question 1 Steps:</em>
pi 3² ---> pi * 9 ---> ≈28.27
<em>Question 1 Answer:</em>
It would have about 28.27 meters² of playable space.
<h3>Question 2:</h3>
For the second problem, it would be much the same as to the first question. There is the same objective to find the area of the circle. Along with that, it gives us a length to work with. This time it is the sprinkler's reach, which would be the radius, or "r" in the equation.
<em>Question 2 Steps:</em>
pi 5² ---> pi * 25 ---> ≈78.54
<em>Question 2 Answer:</em>
The sprinkler would have about 78.54 feet² of space that it can reach.
