The area of the circle is 28.26 in²

<u>Explanation:</u>

Given:

Radius of the circle, r = 3 in

Area of circle, A = ?

We know:

Area of circle = πr²

The value of π is 3.14

Thus,

A = 3.14 X (3)²

A = 3.14 X 9

A = 28.26 in²

Therefore, the area of the circle is 28.26 in²

There cannot be more than two because there are only two vowels, e and a. But it has to be 4 lettered, which limits a lot of option, so there can only be one 4-letter code.

People attending a football game either supported the home team or the visiting team. If 1369 of the people attending supported
Anna [14]

Answer:

37%

Step-by-step explanation:

To find the percentage of people that supported the home team, we need to find the total number of people.

This is because the percentage of people supporting the home team will be given by:

Number of people supporting home team / total number of people

The total number of people is the people supporting the home team plus the people supporting the visiting team:

1369+2331=3700

<u>Therefore, our percentage will be:</u>

1369/3700

Plug this into our calculator and we get:

0.37

Convert that a percentage for a final answer of 37%

Jackie ordered a set of wood and metal clothes pins. Of the 276 pins, 172 were wood. What percentage of the clothes pins were me
timurjin [86]

We know that 172 of them were wood, so the rest are metal. To find that number we do:

276 - 172 = 104 metal pins.

To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:

104/276 is about 0.3768.

Multiply this by 100:

37.68

So, the percent of metal pins is 37.68%.
