suppose 25 out of 175 people said they like to play disc golf and out 5 out of every twelve of the players have a personalized b
Serhud [2]
We have \frac{5}{12} of 252 people who have a personalized black disc

Number of people who would have personalized flying disc = \frac{5}{12}*252= \frac{2*252}{12}=105 people

Then we work out the number of people who like to play disc golf:
\frac{25}{175}*105= \frac{25*105}{175}=15 people

So we have 15 people who like to play disc golf and have personalised black disc.

What is the area of a sector with a central angle of (2pi/3) radians and a diameter of 12 in?
Stels [109]

Answer:

The area of the sector is 37.68\ in^{2}

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

A=\pi r^{2}

we have

r=12/2=6\ in ----> the radius is half the diameter

substitute

A=(3.14)(6)^{2}

A=113.04\ in^{2}

step 2

Find the area of a sector with a central angle of (2pi/3)

Remember that

The area of 113.04\ in^{2} subtends a central angle of 2\pi \ radians

so

by proportion

Let

x----> the area of the sector

\frac{2\pi}{113.04}=\frac{(2\pi/3)}{x}\\ \\x=113.04*(2\pi/3)/(2\pi)\\ \\x=37.68\ in^{2}
