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

Answers

Answer 1

Answer: 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'.

Answer 2

Answer:
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 .

In a salsa recipe, the number of tomatoes added is proportional to the amount of salt added. This graph shows the relationship.What is the unit rate for the situation?

A.

3 tomatoes per teaspoon of salt

B.

6 tomatoes per teaspoon of salt

C.

18 tomatoes per teaspoon of salt

D.

108 tomatoes per teaspoon of salt

Answers

The unit rate for the situation is 3 tomatoes per teaspoon of salt.

The equation of a straight line is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept and y, x are variables.

y represent the number of tomatoes added and x represent the number of teaspoon of salt.

Given the equation of the line is: y = 3x

The unit rate of the graph is equal to the slope of the graph (i.e. 3). Hence:

The unit rate for the situation is 3 tomatoes per teaspoon of salt.

For this case, the first thing you should keep in mind is that the generic equation of the line is:

Where,

m: slope of the line or rate of cam.

b: cutting point with vertical axis.

We note that for this case, the equation of the line is:

Therefore we have:

This means that 3 tomatoes are added for each teaspoon of salt.

A dog runs 9.5 mi in 0.5 h. The distance the dog travels varies directly with the amount of time it runs.How many miles will it run in 1.75 h?

mi

Answers

We divide 9.5 / 0.5 to see how much it runs in 1 hour.

9.5 / 0.5 = 19

So it runs 19 miles in 1 hour.

Now we multiply 1.75 to 19 miles.

1.75 * 19 = 33.25

So he will run 33.25 miles in 1.75 hours.
