The meaning of circumference is to find the distance around a circle or in other words the perimeter of the circle. The circumference of a circle can be calculate by using the formula C=2πr or C=πd.

In this exercise is given that a circle has a diameter of 8.4 centimeters, and it is asked to find its circumference in terms of pi. In this problem the diameter of the circle is given, so in this case the formula C=πd would be used, where d represents the diameter.

C=πd
C=8.4π cm 

The circumference of the circle in terms of pi is 8.4π cm or 26.39 cm.

<h3>What is a rectangle?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

Shelley plans to enclose the patio with fencing.

The dimension of the patio is 12 meters by 6 meters.

Then the perimeter of the patio will be

Perimeter = 2 (12 + 6) - 12

Perimeter = 2 x 18 - 12

Perimeter = 36 - 12

Perimeter = 24 meters

If fencing costs $5 per meter.

Then the cost fence to enclose the patio will be

Cost = 5 x 24

Cost = $ 120

Can you write to me explaining this please
Mnenie [13.5K]

Answer:

In addition, from the response shown, using a graphical calculator brings the following benefits:

1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.

2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.

3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.
