Answer:

Radius: 8

Circumference: 50.27

πr^2 = Area of circle

201.06 = πr^2

divide by pi

201.06 / π = 63.9993857161 = 64

64 = r^2

Square root both sides to get radius.

\sqrt{64} = 8

r = 8

Circumference = π x diameter

Diameter = 2 x radius

Circumference = π x 16 = 50.2654824574 = 50.27

Use the permutation formula below to find the number of outcomes when n = 5 and r = 2.
faltersainse [42]

nPr =  \frac{n!}{(n - r)!}

5P2 =  \frac{5!}{(5 - 2)!}  =  \frac{5 \times 4 \times  3 \times 2 \times 1}{3 \times 2 \times 1}  = 20

( 2 x 4 ) x 7 = 2 x (7 x 4 ) What Property does this demonstrate?
Lana71 [14]
Hi There!

<span>( 2 x 4 ) x 7 = 2 x (7 x 4 ) represents the associative property of multiplication. The associative property states of multiplication states, that you can multiply  even  how the numbers are grouped.

You can test this you're self.

1. Multiply 2*4=8    8 *7=56

2. 7*4=28   28*2=56

In conclusion, </span><span>( 2 x 4 ) x 7 = 2 x (7 x 4 ), uses the associative property of multiplication.

Hope this helps :)</span>
