Mathematics

Blizzard [7]4 years ago

Answer:

πr²

Step-by-step explanation:

The surface area of a circle is πr²

Pie is 22/7 or 3.14

While the radius of a circle is any line from the centre of a circle to any part of the circumference of the circle. A diameter is any line that cuts the circle into two equal halves, cutting the circle from the centre.

To get the surface area of a circle, you draw a line from the centre of the circle, and then touch any part of the circumference of the circle. Then you measure the line, that's the radius.

If for instance, the radius gives 7cm, you find the Square, And then multiply it with pie.

22/7 X 7 ²

22/7 X 7 X 7

22 X 7

154cm²

denis23 [38]

Answer:

Step-by-step explanation:

Let 'x' represent the actual salary.

|x - 25,000| <= 1800

- 1,800 <= x - 25,000 <= 1,800

25,000 - 1,800 <= x <= 25,000 + 1,800

23,200 <= x <= 26,800

The range of the salary is the closed interval [23,200, 26,800].

Jayden, Maggy, and Ramon shared $49 in the ratio 2:5:7. How much more did Ramon get then Jayden
Drupady [299]
Since the ratio is 2:5:7, you can set up the equation 2x + 5x + 7x = 49. Solving it will give you 14x = 49 or x = 3.5. This means that Jayden got 7(3.5) = $24.50 and Ramon got 2(3.5) = $7. Therefore Ramon got $24.50 - $7 more than Jayden, which is equal to $17.50.
