Answer:

12π  inches.

Step-by-step explanation:

Area = π r^2 = 36π  (given).

So r^2 = 36  giving r = 6.

The exact circumference = 2 π  r

= 2 π * 6

= 12π.

Answer:

12πin

Step-by-step explanation:

From the question given, the area of the circle is 36πin^2

Recall:

Area of circle = πr^2

36π = πr^2

Divide both side by π

36 = r^2

Take the square root of both side

r = √36

r = 6in

Circumference of a circle = 2πr

= 2π x 6

= 12πin

Adrian can put a total of 1716 combinations in the player. 

The formula to be used is as follows:

total combinations = n!/[r! *(n-r)!]
n = number of disks available  = 13
r = number of disks that be held = 6

= 13! = (13• 12•11•10•9•8•7•6•5•4•3•2•1)/(6! <span>• 7!)
</span>=1716
