The radius of a circle is 15. Using π, which equation expresses the ratio of the circumference to the diameter of a circle?

radius of circle = 15

circumference of circle  = 2πr

                                        = 2*22/7*15

                                        = 44/7*15

                                        = 660/7

                                       = 94.28

diameter of circle = 2r

                              = 2(15)

                              = 30

RATIO = 94.28:30

step-by-step explanation:

hopefully im right

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
