If the circumference of a circle measures 12π cm, what is the area of the circle in terms of π?

1 answer:

5 0

So the formula for the circumference of a circle is π x diameter
Since we know the the circumference already, we just divide that by π:

12π / π = 12

Now we halve the diameter to get the radius:
12 / 2 = 6

The area of a circle is π x radius²
So the area is:

·π x 6² = 36π· (or 113 not in terms of π)

Item 5 Write 77.5% as a fraction or mixed number in simplest form.

jeyben [28]

77.5% can also be written as 77.5/100, but if you're the mathematical notation police, people don't like decimals on a fraction, sooo, an equivalent form is:

= (77.5)/(100) * (2/2)
= 155/200
= 31/40
= 0 31/40

you are assembling desserts with a friend together you can make 12 desserts in 5 minutes. how many can you make in 20 minutes?

Sever21 [200]

You can solve this in two ways.

First way:
Let’s find out how many my friend makes in one minute.
12/5=2.4
He makes 2.4 in one minute. Let’s multiply that by 20 to find what he makes in 20 minutes.
2.4•20=48
My friend made 48 desserts.

Second way:
Let’s make a ratio.
12 desserts:5 minutes
X desserts: 20 minutes
Whatever you do to one side, you have to do to the other. Since you are multiplying the minutes by 4, you have to multiply the desserts by 4.
12•4=48

So, my friend made 48 desserts.
Tell me if this helps!!!

According to the 2010 U.S. Census, there are approximately 8 million people living in Virginia. This is 2.8 million less than 4

grandymaker [24]

Solution: We are given that the population of Virginia is 8 million.

Let x be the population of Nevada.

We are given population of Virginia is 2.8 million less than 4 times the population of Nevada.

$\therefore 4x-2.8=8$
