The circumference is __

Anestetic [448]

Answer:

As we know that there is a radius which is 2 cm

so 

circumference = 2 π r

 = 2 * 22/7 * 2

 = 12.57cm

it's circumference is 12.57 cm

PLEASE HELP!!!!!!!! (ALGEBRA II)

qwelly [4]

Answer:

-4 4 4.5 8 20.5 32

Step-by-step explanation:

f $\circ$ g(x) = f(g(x))

Given, f(x) = 2x²

and g(x) = x - 2

Now f(g(x)) = f(x - 2) = 2(x - 2)²

We know that (a - b)² = a² - b² + 2ab

Using this we expand f(g(x)). We get:

f(g(x)) = 2{x² - 4x + 4}

Similarly, g(f(x)) = g(2x²) = 2x² - 2

Now, f(g(-2)) = 2[(-2)² - 4(-2) + 4] = 2(16) = 32.

Also, g(f(-2)) = 2[(-2)² - 2] = 2(2) = 4.

f(g(3.5)) = 2{(3.5)² -4(3.5) + 4} = 2[12.25 - 14 + 4] = 2(2.25) = 4.5.

g(f(3.5)) = 2{(3.5)² -2} = 2{12.25 - 2} = 2(10.25) = 20.5.

f(g(0)) = 2{0 - 4(0) + 4} = 2(4) = 8.

g(f(0)) = 2{0 - 2} = 2(-2) = -4.

Arranging them in ascending order, we get:

-4 4 4.5 8 20.5 32 would be the sequence.

Can someone please help me?

Alisiya [41]

Answer:

Step-by-step explanation:

That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.

Area of square = 1.6 × 1.6

Area of square = 2.56 m squared

Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².

Area of circle = 8.0384

Divide that by 4 to get 2.0096.

Add 2.0096 to 2.56 to get the total area, which is

4.5696 or 4.6 rounded (choice D)

find the circumference and the area of the circle with the radius 9m use the value 3.14 for it do not round your answer be sure

kirill [66]

Explanation:

The circumference and the are of a circle with radius r

are:

$\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}$

If we use pi = 3.14 and the radius is 9m:

$A=3.14\cdot(9m)^2=3.14\cdot81m^2=254.34m^2$ $C=2\cdot3.14\cdot9m=56.52m$

Answers:

• Area: ,254.34 m²

,

• Circumference: ,56.52 m
