    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)

    180 degrees ? @phi

    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)

    180 and 360 sound like degrees. see http://www.mathplanet.com/education/pre-algebra/more-about-equation-and-inequalities/calculating-the-circumference-of-a-circle

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

    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
