Mathematics

Answer: The area of the circle= 56.25/π

Step-by-step explanation: With the circumference of the circle already given, we can work backwards to determine the value of the radius.

The circumference of a circle is calculated as

Circumference= 2πr

Since the circumference is already known, we can now express it as;

15 = 2πr

Divide both sides of the equation by 2

7.5 = πr

If we cross multiply we now have

7.5/π = r

Having calculated the radius as 7.5/π, the area can be derived as

Area d a circle = πr²

Area of a circle = π x (7.5/π)²

Area of a circle = π x (56.25/π²)

Area of a circle = 56.25/π

The area of the circle in terms of pi is given as 56.25/π

Which point is a solution to the system of inequalities below?
vodomira [7]

The ordered pair which is a solution to the given inequality is: C. (2, 1).

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

Next, we would test the ordered pair with the given inequality to determine a solution as follows:

For ordered pair (4, 4), we have:

3x + 2y < 15

3(4) + 2(4) < 15

12 + 8 < 15

20 < 15 (False).

For ordered pair (3, 3), we have:

3x + 2y < 15

3(3) + 2(3) < 15

9 + 6 < 15

15 < 15 (False).

7x - 4y > 9

7(3) - 4(3) > 9

21 - 12 > 9

9 > 9 (False)

For ordered pair (2, 1), we have:

3x + 2y < 15

3(2) + 2(1) < 15

6 + 2 < 15

8 < 15 (True).

7x - 4y > 9

7(2) - 4(1) > 9

14 - 4 > 9

10 > 9 (True)

For ordered pair (1, 0), we have:

3x + 2y < 15

3(1) + 2(0) < 15

3 + 0 < 15

3 < 15 (True).

7x - 4y > 9

7(1) - 4(0) > 9

7 - 4 > 9

3 > 9 (False)
