what does r n and s stand for?
if point P rotated 1.5 times along a circle of radius 1 unit then P travels _______ units
can you actually give me the question the exact way it was given to you
that's it already @shinebrightlikeadimon
well contact your teacher the idiot that gave you this problem doesn't know how to explain it properly
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
but i still dont know how to do this?
Do you see what the formula for the circumference (called C) is ?
yup c=2 pi r
now look at your question. what is r ?
and what number do you use for pi ?
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
oh i see = 9.42 ? @phi
