Answer:
Step-by-step explanation:
The general circle equation is
where r is the radius.
Since we know all the information just plug it in the equation above.
Simplify 3 squared.
1) General choice of shoes:
<span>C(6,1) = choose the matching pair = 6 choices. </span>
<span>C(10,1) = 1 shoe from the other 10. </span>
<span>Now you cannot choose the mate of that one, </span>
<span>so you have 8 other shoes to choose from. </span>
<span>6 * 10 * 8 = 480 choices of "4 shoes". </span>
<span>But then we must divide by 2, because the last two shoes </span>
<span>could be chosen in either order. </span>
<span>That gives 240 choices </span>
