The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
<span><span><span>82</span>=64</span><span><span>82</span>=64</span></span>choices for that.
Now, for the second one, we can't be in the row or column of that first one, so leaving us with <span><span><span>72</span>=49</span><span><span>72</span>=49</span></span> choices.
Then so on, we have <span><span><span>62</span>=36</span><span><span>62</span>=36</span></span> for the third one, <span>2525</span> for the fourth one, and so on <span>……</span>
But, however, we have to remember the rooks are not labeled, thus it doesn't matter specifically about a specific rook's position.
Thus, we have a total of <span><span><span><span>(8!<span>)2</span></span><span>8!</span></span>=40320</span><span><span><span>(8!<span>)2</span></span><span>8!</span></span>=40320</span></span> ways.
Step-by-step explanation:
position your compass at point A and using the same distance mark arcs on line AB(mark the point it meets the line D)and AC(mark the meeting point of the arc and the line E).Place your compass at D and draw an arc at the middle of the angle,using the same measurements position your compass at point E and draw an arc.Where the two arcs meet label F using a ruler draw a straight line from F to meet point A.
Note;the width of the compass when making the arcs should be the same always
