Area of a circle is 80 cm². Work out the circumference of the circle.
GuDViN [60]

Answer:

The circumference of circle is: 31.714 cm

Step-by-step explanation:

Let C be the circumference of the circle

And A be the area of circle

It is given that:

A = 80cm^2

We have to find the radius first so that it can be used to find the circumference

The area of circle is given by the formula:

A = \pi r^2

Putting the value of area

80 = 3.14 * r^2\\\frac{80}{3.14} = r^2\\r^2 = 25.477

Taking square root on both sides

\sqrt{r^2} = \sqrt{25.477..}\\r = 5.0475\ cm

Now

C = 2\pi r

Putting the value of radius

C = 2 * 3.14 * 5.05\\C = 31.714\ cm

Hence,

The circumference of circle is: 31.714 cm

Please help me answer this question
Setler79 [48]

Answer:

x = 90 degrees and y = 43 degrees

Step-by-step explanation:

We have an isosceles triangle here, since the length of AB equals the length of AC.

That also means that angle ABC equals angle ACD = 47 degrees.

The sum of the interior angles of a triangle equals 180.

47 + 47 + 2y = 180

94 + 2y = 180

2y = 86

y = 43 degrees

x + 43 + 47 = 180

x + 90 = 180

x = 90

Tell which transformation is shown by the change in ordered pairs ​
iren [92.7K]

Answer:

Translation

Step-by-step explanation:

Transformation is the movement of objects in the coordinate plane. It can be through any of translation, reflection or rotation. The kind of transformation that occurs in ordered pairs is translation e.g if the ordered pair is (1, 4) x = 1, while y = 4. if it is translated we have (4, 1) such that x is now 4 while y is 1
