Answer:169pi

Step-by-step explanation:

Circumference(c)=26pi

Circumference(c)=2 x pi x radius(r)

26pi=2pi x r

Divide both sides by 2pi

26pi/2pi=(2pi x r)/2pi

13=r

Radius(r)=13

Area of circle=pi x r^2

area of circle=pi x 13^2

Area of circle=169pi

The range of y= sin x is

kolezko [41]

Given:

y = sinx

Required:

To find the range.

Explanation:

The graph of the sine function is as follows:

We can observe from the graph that the values of y lie between -1 to 1.

So the range of the sinx function is [-1, 1].

Final Answer:

The range of sinx function = [-1, 1].

True [87]

Answer:

Numbers that never end and don't repeat either. In definition, an irrational number is a number that cannot be written as a simple fraction.

Step-by-step explanation:

Examples of irrational numbers are:

*All square roots of natural numbers, except perfect squares, are irrational.:

- $\sqrt{97}$ - $\sqrt{2}$ - $\sqrt{1001}$

*Pi is an irrational number

- $\pi$

Which function families have vertical symmetry?

Nady [450]

The functions which are even are symmetric to y-axis. By even functions, it means that f(x) = f(x) for all the domain values. Thus even functions for example, x^2, 1+x^2, cosx, x^4 all follow the conditions i.e. f(x) = f(x) and thus they are symmterical to y-axis.

Here are the first five terms of an arithmetic sequence.

Assoli18 [71]

Answer:

The nth term of an AP will be 27 -7n.

Step-by-step explanation:

First five terms of the Arthemetic Sequence is given to us , which is 26 , 19 , 12 , 5

Hence here Common Difference can be found by subtracting two consecutive terms . Here which is 19 - 26 = (-7) .

Here first term is 26 .

And the nth term of an AP is given by ,

★ T_n = a + ( n - 1) d

Substituting respective values ,

⇒ T_n = a + ( n - 1 )d

⇒ T_n = 26 + (n - 1)(-7)

⇒ T_n = 26 -7n+1

⇒ T_n = 27 - 7n

<h3>Hence the nth term of an AP can be found using T_n = 27 - 7n. </h3>
