Answer 3

there @shinebrightlikeadimon

Answer 4

can you actually give me the question the exact way it was given to you

Answer 5

that's it already @shinebrightlikeadimon

Answer 6

Answer 7

lol

Answer 8

@Mertsj

Answer 9

@eliassaab @phi

Answer 10

I assume they mean 1.5 times around the circle.

find how far 1.5 loops around the circle is. (1 loop is the circumference)

Answer 11

180 degrees ?

@phi

Answer 12

I think they want the distance around the circle 1.5 times.

First step: what is the distance if you go around the circle once?
(the distance is called the circumference)

Answer 13

360? @phi

Answer 14

180 and 360 sound like degrees.

Answer 15

i see

Answer 16

but i still dont know how to do this?

Answer 17

@phi

Answer 18

Do you see what the formula for the circumference (called C) is ?

Answer 19

yup c=2 pi r

Answer 20

now look at your question. what is r ?

Answer 21

1

Answer 22

and what number do you use for pi ?

Answer 23

3.14

Answer 24

now use those numbers in your formula
c= 2*pi*r

replace pi with 3.14 and r with 1
c= 2*3.14*1

what is c ?

Answer 25

c=6.28

Answer 26

that is the distance once around the circle.
they want the distance if you go 1.5 times around the circle.
that means multiply c by 1.5

Answer 27

oh i see

= 9.42 ?
@phi

Answer 28

thank you
