Question
In the xy-plane, the graph of the given equation is a circle. What is the radius of this circle?
The correct answer is: 9
The general equation for a circle is , where (h. k) is the center and r is a radius.
Explanations:
Step 1 of 2:
The given equation for the circle is
Now,
Step 2 of 2:
Now comparing equation (*) with the general equation for circle, we get r = 9.
Final Answer:
The radius of the circle is 9 unit.

For part of a trip, a car traveled directly away from its starting point at a constant speed. The graph shows the car's distance from its starting point, in miles, for times from 2.0 hours to 2.5 hours after the start of the trip. What was the speed of the car, in miles per hour, during this part of the trip?
Distance divided by time is the formula for speed. Both meters per second (m/s) and kilometers per hour (km/hr) are used to measure speed.
The amount of distance traveled at a given velocity is shown by a speed formula. The measurement of speed is the distance covered in a predetermined period. The car traveled directly away from its starting point at a constant speed can be determined by knowing the distance it traveled and the time it took. The time graph separation is a line graph that shows the results of the distance versus time analysis. It is easy to create a distance-time graph. To begin, take a piece of graph paper and draw two parallel lines that meet at the letter O. The X-axis is the horizontal line, and the Y-axis is the vertical line. A graphic that shows the distance traveled in a specified amount of time is known as a distance-time graph. In other words, it provides information regarding the vehicle's speed over a specific distance. The graph makes the numerical statistics for time and distance easier to interpret. The graph also shows how far the car has traveled at any given moment. Finding the changing speed at different distances can be done with the help of a distance-time graph.
