In a track field competition, A discus has a radius of 11 centimeters. What is the circumference, I centimeters, of the discus?

Morgarella [4.7K]

Given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.

<h3>What is the circumference of the discus?</h3>

Note that; a circumference is the perimeter of a circle or ellipse.

It is expressed as C = 2πr

Where r is the radius and π is the constant pi ( π = 3.14 )

Given that;

Radius of the discus r = 11cm
Circumference C = ?

C = 2πr

C = 2 × 3.14 × 11cm

C = 69.08cm

Therefore, given the radius of the discus used in the track field competition, the circumference of the discus is 69.08cm.

Five balls are chosen from a bag of eight blue balls, six red balls, and five green balls. How many of these five-ball selection

Harlamova29_29 [7]

Using the combination formula, it is found that six of these five-ball selections contain exactly five red balls.

The order in which the balls are selected is not important(as balls A, B, C, D and E is the same outcome as balls B, A, C, D and E), hence the <em>combination formula</em> is used to solve this question. If the order was important, then the permutation formula would be used.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, five red balls can be chosen from a set of six, hence the number of selections is the combination of 5 elements from a set of 6, that is calculated from the formula given above:

$C_{6,5} = \frac{6!}{1!5!} = 6$

Hence six of these five-ball selections contain exactly five red balls.
