If the circumference of a circle is 2pi, what is the area?

Answers

Circumference of a circle= 2 * pi * r

Plug in what we know: 2pi = 2 * pi * r

Divide 2 pi to both sides: r = 1 (anything divided by itself is equal to 1)

Area = pi * r^2

Plug in what we know: A = pi * 1^2
A = pi * 1 ==> A = 1 pi

So the area is '1 pi' or just 'pi'.

The circumference of a circle is (pi) x (diameter).

The circumference of this circle is 2pi, so

2 pi = (pi) x (diameter).

So the diameter of this particular circle is 2,
Its radius is 1/2 of the diameter, so radius = 1.

The reason we need to know the radius is
because it's needed to find the area.

The area of any circle is (pi) x (radius squared).
For this particular circle ...

Area = (pi) x (1 squared) = pi square units .

A model spaceship cost 15.99 before tax the tax on the model spaceship is 8%

Answers

Hi there!

The tax on the spaceship is 8% of 15.99

The word "of" is the same thing as a multiplication sign.

8% of 15.99 = 8% × 15.99

8% = 0.08

8% × 15.99 = 0.08 × 15.99

0.08 × 15.99 = 1.2792

15.99 + 1.2792 = 17.2692

Your answer is: The final price including tax for the spaceship is about $17.27

There you go! I really hope this helped, if there's anything just let me know! :)

15.99 * .8 = 12.79

15.99 + 12.79 = 28.78

the answer is $28.78 :)

What is the y-intercept of the line shown? (The graph is down below)

Answers

Hello!

The y-intercept is where the line hits the y-axis. By looking at the graph, we can see that this line intersects with the y-axis at point (0,3). We just write the y-intercept as this y-value.

Therefore, our answer is C) 3.

I hope this helps!

How do you convert kilometers to meters??

Answers

1km=1000m
If u had a number like 23KM, you would have to multiply it by 1000 but if the number is 23M than you would have to divide it by a thousand to get your kilometers.

To change km into m you must multiply by 1000
The word 'kilo' means 1000
Think of km as k x m (1000 x m)
1 km = 1000m
9 km = 9000m
