You have to convert millimeters in meters, 1000 mm = 1 m,

6000 mm = 6 m

6 m is your answer.

If you double the radius of a circle, then you will quadruple the circumference of the circle

alexira [117]

Answer:

False

Step-by-step explanation:

No options is attached to the question. However, I'll assume it's a true or false question.

Represent the radius with r.

The circumference is calculated as:

X = 2πr

When the radius is doubled, the new radius R is

R = 2r

And the new circumference, C is:

C = 2πR

Substitute 2r for R

C = 2π * 2r

C = 4πr

Factorize the above equation.

C = 2 * 2πr

Recall X = 2πr;

The expression becomes:

C = 2 * X

C = 2X

This means that the circumference is doubled, not quadrupled.

Hence, the statement is false.

After 22 weeks of training, Amanda learned a total of 55 appetizer recipes. After 6 weeks of training, she will learn

Artist 52 [7]

Answer: 15

Step-by-step explanation:

My answer is correct because, if in 22 weeks she learned 55 recipes of appetizers, the we have to divide 55 by 22. And 55 divided by 22 equals 2.5. So now since we have that and they are asking us what would it be for a total of 6 weeks then we just have to multiply 2.5 and 6. And 2.5 times 6 equals 15.
