What you do is you do 93 x 81.
93
x 81
------------

That's the square footage. Hope it helps!
The answer is B(11, 2sqrt(12) )
proof
the main equation of the circle is (x-x1)²+(y-y1)²=R²
where C(x1, y1) is the center
so if the center is the origin, it is O(0,0), and the equation becomes
<span> (x)²+(y)²=R²
</span>and the circle passes through the point (-5,2) so we can write
(-5)²+12²=R², it implies R= sqrt(25+144)=sqrt(169)=13
and for <span>B(11, 2sqrt(12) ) </span>11²+ (2sqrt(12))²= 121 + 48= 169= 13
it is checked.

Answer:
50 legs
Step-by-step explanation:
We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate 
, right?
Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want 
.
We multiply it out to get 
.
We add these up to get 
.
So, our answer is 
legs.
