Abirthday cake is sliced into 8 equal pieces. the arc length of one piece of cake is 6 in. find the diameter of the cake. round your answer to the nearest inch.

12

Step-by-step explanation:

the diameter goes across the entire circle ( one side to the other) so add one piece of cakes length to the other and you get your diameter  

6+6=12

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
