Step-by-step explanation:
Formula to get the area of a circle 'A' =
where r = radius of the circle
Given in the question,
Area of the circle = 153.86 square meters
By putting the values in the formula,
153.86 = πr²
r =
r =
r = 7 meters
Diameter of circle = 2 × (radius of the circle)
= 2 × 7
= 14 meters
Therefore, diameter of the circle is 14 meters.
Option (2) is the answer.
Answer:
The system of equations has one solution at (-4, 4).
Step-by-step explanation:
We are given the system of equations:
We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.
Therefore, our system now becomes:
Now, we can add these two equations together and solve for y.
Now, we can substitute our value for y into one of the equations and solve for x.
Therefore, our final solution is (-4, 4).
