Step-by-step explanation:
Best Answer:<span> </span><span>So first we need both areas, then we can relate them, and then divide the circle by the square:
A(circle) = πr^2
A(square) = L*W or (2r)*(2r) which is (2r)^2
For the square, we know this is true because because the radius is half the diameter, so if we multiply the radius by 2, we get the length of one side of the square. We also know that the lengths of both sides of the square are the same by definition of a square.
Ratio: (πr^2)/(4r^2) = π/4</span>
Answer:
21a+77b
Step-by-step explanation:
7x3=21
7x11=77
Answer:
Step-by-step explanation:
Use the slope formula so y2 - y1 / x2 - x1 [the numbers are subscripts]
So -8 - (-3) / -2 - (-6) so -8+3/-2+6, therefore -5/4
The circle of radius r centered at (h, k) has equation
.. (x -h)^2 +(y -k)^2 = r^2
Selection A is appropriate.

It would be helpful if you would use appropriate math symbols. 102 is very different from 10^2. (Copying and pasting does not work--editing is needed.)
