The area of the circle above is 314 units2. What is the circumference of the circle? use 3.14

And the circumference is given by this formula:

And replacing the value fo r we got:

And then the final answer would be 62.8 units for the circumference.

Step-by-step explanation:

For this case we know that the area for a circle is given by:

And we know that

We can find the radius from the previous formula like this:

And the circumference is given by this formula:

And replacing the value fo r we got:

And then the final answer would be 62.8 units for the circumference.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
