Answer 3

omg no one is answering its a 7th grade question

Answer 4

is anyone gonna try to answer?

Answer 5

as we know v=Rα

Answer 6

and α=2πN where N is the number of revolution s per second

Answer 7

then what do i do

Answer 8

eegggh so amny marks

Answer 9

so if we substitute we get v=(d/2)2πN

Answer 10

whats with the infinite question marks

Answer 11

replace and find N you get wait

Answer 12

C 11.9 :)

Answer 13

what do i replace with wat?

Answer 14

25 with d?

Answer 15

oh wait i got it thanks

Answer 16

ok so i told you v=d2pπN so N=(V)/(d2π)

Answer 17

and v=15 and d=24 and pie=3.14 so N=15/(24*3.14)=0.199rotations/s but they want it per minute so N=0.199*60=11.9rotations/min

Answer 18

your welcome :)
