For an outdoor concert by the city orchestra, concert organizers estimate that 19 comma 000 people will attend if it is not rai

My name is Ann [436]

<h2>Answer:</h2><h2>The expected number of people who will attend this concert = 2260</h2>

Step-by-step explanation:

The concert organizers estimate people will attend if it is not raining = 19000

If its raining people will attend = 4000

On the day of the concert, meteorologists predict a 90% chance of rain.

This means 10 % chance of not raining

The expected number of people = 90% (4000) + 10% (19000)

= 360 + 1900

= 2260

The expected number of people who will attend this concert = 2260

Problem A park has a large circle painted in the middle of the playground area. The circle is divided into 444 equal sections, a

Vladimir79 [104]

Answer:

25 $\pi\ m^2$

Step-by-step explanation:

Given that:

A large circle in the park has its middle part painted.

The circle is divided in 4 equal parts.

Radius of the circle = 10 meters

To find:

Area of each section of the circle, $A$ = ?

Solution:

Here, we need to find the area of the bigger circle first and then need to divide it into 4 equal parts to find out the answer.

First of all, let us have a look at the formula for area of a circle with given radius $r$ :

$Area = \pi r^2$

Here, $r = 10 m$

Putting the value in the above formula, we get:

So, area = $\pi 10^2 = 100\pi\ m^2$

Now, there are 4 equal parts of the circle, therefore area of each section will be equal.

Area of each section of the circle:

$\dfrac{100\pi}{4} = \bold{25 \pi}\ m^2$
