the area of a circle is 81 pi m^2. what is the circumference, in meters? express your answer in terms of pi.
mestny [16]
<h3>Answer:    18pi</h3>

============================================================

Explanation:

The area 81pi square meters leads to the radius 9 meters

Use the formula A = pi*r^2 to see why this is the case. You plug in A = 81pi and solve for r to get r = 9.

-----------------

Once you know the radius, you can determine the circumference C

C = 2*pi*r

C = 2*pi*9

C = 2*9*pi

C = 18pi

The circumference is the perimeter, or distance, around the circle.

(f o g)(x)

g(x) = x + 2

Since it’s telling you to use g(x), you use (x + 2) as your new x value for function f.

f(x + 2) = 5(x + 2) + 5
= 5x + 10 + 5
= 5x + 15

The length of side X is 36.25 cm to the nearest hundredth of a centimeter what is the length of y
goldenfox [79]

Answer:

<h3>The length of y is 62.82 cm.</h3>

Step-by-step explanation:

We are given a right triangle with an angle 30°.

Opposite side of angle 30° is x and adjacent side is y.

Also, given length of side x=36.25 cm.

In order to find the value of y, we need to apply tangent trigonometrical ratio.

We know,

tan \theta =\frac{Opposite \ Side}{Adjacent \ Side}

Therefore,

tan \theta =\frac{x}{y}

Plugging values of \theta =30^o and x=36.25, we get

tan 30^o=\frac{36.25}{y}

Plugging value of tan 30^o=0.577 in above equation, we get

0.577=\frac{36.25}{y}

On multiplying both sides by y, we get

0.577\times y=\frac{36.25}{y}\times y

0.577y=36.25

Dividing both sides by 0.577, we get

\frac{0.577y}{0.577} =\frac{36.25}{0.577}

y=62.82

<h3>Therefore, the length of y is 62.82 cm.</h3>
