Answer:

The circumference is tripled

Step-by-step explanation:

If the radius started as 2 the area would be 12.57 and the circumference would be 12.57.

Then if multiply the radius by 3 it would be 6 and the area would be 113.1 and the circumference would be 37.7.

12.57x3=37.7

Therefore the circumference triples when the radius is multiplied by 3.

Answer:

I think that both are true...

If it's one, it's the circumference.

Step-by-step explanation:

So say the radius is x.

The area is πx^2

The circumference is 2xπ

If you multiply it by 3:

The area is 3πx^2

The circumference is 6xπ

A graph has a constant of proportionality of 2.54. Let y represent centimeters and x represent inches. What is the unit rate of
Helga [31]

Answer: 2.54 is the rate of the given equation.

Step-by-step explanation:

Let x is the independent variable and y is the dependent variable.

Since, By the definition of proportionality,

y = k x

Where k is the constant of proportionality.

And, Here k = 2.54

Thus, the equation of line is,

y = 2.54 x

since, rate of the equation is the slope of the line.

And, the general equation of line

y = m x +c

Where, m is the slope of the line.

By comparing the equation of line y = 2.54 x  with this.

The slope of the line = 2.54

Therefore, 2.54 is the rate of the given equation.

Step-by-step explanation:

Let's figure out where the ant is after each step.

Step 1

Start at      +3.0

Move left  <u> - 1.5 </u>

Now at       +1.5

Step  2

Start at           +1.5

Move right  <u> + 4.9 </u>

Now at         +6.4

Step 3

Start at      +6.4

Move left <u> - 7.6 </u>

Now at      -1.2

The ant is now at -1.2 cm.
