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)

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)

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

3.14

2
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 ?

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
