    angles are like oragnes sides are like coconuts they are not same things, so you cant add/subtract ok

    Okay. So how would I find out what the other angle is?

    use triangle sum property the angles in a triangle add up to 180 : x + 45 + 90 = 180

    Yes, both angles are equal... that means we have a 45-45-90 triangle |dw:1434460608243:dw|

    30 is the radius of given circle, not circumference circumference is the length around circle (also called perimeter)

    look up ur notes if you don't remember the formula for circumference

    leave it in terms of \(\pi\), do not simplify

    nope, what formula are you using ?

    I was using the formula to find the circumference and got 188.5

    what is it

    2*pi*r

  32. ganeshie8

    Yes, circumference = 2*pi*r = 2*pi*30 = 60*pi
