Answer:

<h2>9498.5 m</h2>

Step-by-step explanation:

We know that the Circumference = 3454 cm

And we also know that the formula for the Circumference of Circle is,

2\pi \times r

So we can put the equation this way,

3454 = 2\pi \times r

So we can solve for 'r'

3454 = 2 \times 3.14 \times r \\ 3454 = 6.28r \\ r   =   \frac{3454}{6.28}  \\ r = 550

Now we have radius and we can solve for the area of the circle,

\pi \times  {r}^{2}

3.14 \times 550 \times 550  \\  = 949850

We can convert this to meter,

9498.5 m

I am not sure if this is correct just let me know thanks :)

Which equation can be used to find the measure of angle LJK?
UkoKoshka [18]
Depending on what type of triangle it is, for a right triangle you would use sin inverse=(opposite/hypotenuse), cos inverse=(adjacent/hypotenuse), or tan inverse=(opposite/adjacent). For any other triangle you would refer to the Law of sines where side a/sine of angle A=side b/sine of angle B and same goes for C

In a box there are two prizes that are worth $4, a single prize worth $20, and a single prize worth $200. A player will reach in
Ronch [10]

Answer:

57

Step-by-step explanation:

The player has a 1/4 chance of drawing any of the 4 prizes. This means that the probability of drawing a prize of $4 is 1/2 because there are 2 prizes worth of $4. The probability of drawing a prize of $20 is 1/4 and the probability of drawing a prize of $200 is also 1/4. To find the fair price of the game, we have to calculate the expected value that the player will gain. This can be obtained by multiplying any possible value of a price for the probability of drawing a prize of that value and adding all the obtained values togueter. Thus, the fair price of the game is

4 * \frac{1}{2} + 20 * \frac{1}{4} + 200 * \frac{1}{4} = 57
