The equation for circumference is: 2 x Pi x r

You used the diameter (9), rather than the radius. The radius is the diameter divided by 2. Therefore, your equation should be: 2 x 3.142 x 4.5, NOT 2 x 3.142 x 9.

This means your answer should be 28.3. Hope this helps! Just a minor mistake (:

The formula for circumference is 2\pir, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3

The number of paper clips that crystal has is 42 divided by the number of paper clips that gayle has. If gayle has 11 more paper
Rom4ik [11]

Answer:

• Gayle: 14

• Crystal: 3

Step-by-step explanation:

Let g represent the number of paperclips Gayle has. Then 42/g is the number Crystal has. The relationship between the two numbers is said to be ...

g - (42/g) = 11

Multiplying by g gives ...

g^2 -42 = 11g

g^2 -11g -42 = 0 . . . . subtract 11 g to put into standard form

To factor this, you are looking for two factors of -42 that sum to -11.

-42 = -42·1 = -21·2 = -14·3 = -7·6

You can see that -14 and 3 sum to -11, so the factoring is ...

(g -14)(g +3) = 0

g = 14 . . . . . . . . . . makes the product zero. (The g=-3 solution is extraneous.)

Gayle has 14 paperclips and Crystal has 3.

In how many ways can five basketball players be placed in three positions?
Georgia [21]

Answer:

10 ways

Step-by-step explanation:

The number of ways in which five basketball players could be placed in three positions is:

5C_{3} = \frac{5!}{(5-3)!3!}

      = \frac{5!}{3!2!}

      = \frac{5*4*3*2!}{3*2*2!}

      = 5 × 2

     = 10

The basketball players can be arranged in 10 ways.
