    if something is 30' in
    diameter and circular in
    shape does that mean
    it's 30' on all sides?
    the square footage is
    706, how do you get 706
    out of 30'?

    Uh, a circle doesn't have any sides.

    The diameter is a straight line passing through the center of the cicle dividing it in half. Your diameter is 30'. The radius(half of the diameter) would be 15'. Ummm,this is about as far as I can go. Is this a trick question? [img]smilies/confused.gif[/img]

    Area of a circle = pi * r2 (squared)

    So... in this case 3.14 * (15 * 15) = 706.5

    Hope this helps

    Oh... r is the radius, which, stated above is half the diameter.

    Almost looks kinda like having your own mini-Kingdome!

    Well, a room that was 26.5 X 26.5 would be 702.25 square feet - so you can compare it to that.

    Take a string 15 feet long, post one end of it in the ground, on the other end, chalk or something. Now draw your circle. Voila, a diameter of 30 feet.

    so what your saying JETM
    is if you put a stake in the ground, tie a 15' piece of string to it and chalk that going all the way around that would be the diameter.

    Hey, topik killer,

    Circumference is the distance all the way around the circle, or the perimeter of a circle. If you walked around in a circle, you would walk the circumference.

    Diameter is how wide the circle is at its widest point. If you walked from one edge of a circle, through the middle, to the opposite edge, you would walk the diameter.

    Radius is half of the diameter, or the distance from the center of the circle, to the edge.

    The chalk circle would measure the circumference. For your circle, that would be 94.2 feet (3.12 x 30).

    The diameter is the line formed if you were to start at the piece of chalk. Walk the straight line to the nail in the ground at the center of the circle and then straight through to the other side of the circle (30 feet).

    If the graphic shows here, the blue circle is the circumference (94.2 feet). The red line is the diameter (30 feet).
