The term "radius" only applies to circles, and is half of the circle's width (or diameter). For rectangles, you have a width and a height, and the area is calculated by multiplying width by height. A square's width and height are equal, so if a square is 5" wide, then the area is 25 square inches (25in2).
Circle areas are calculated by multiplying the radius by itself, and multiplying the result of that by pi (π), or about 3.14. A circle with a radius of 5" would be 3.14*5*5, or 78.5in2 (78.5398 to be more accurate).

What is the area of the rectangle if the radius of each circle is 6cm?
It depends on the relationship between the rectangle and the circles.
A 5 by 12 is inscribed in a circle what is the radius of the circle?
The center of the rectangle to the corner of the rectangle is the radius of the circle. That can be found using the distance formula sqrt((5/2)^2+(12/2)^2) = 6.5 = r 5/2 is half the height of the rectangle and 12/2 is half the height of the rectangle. radius = 6.5
What is the area of the rectangle of largest area that can be inscribed in a circle of radius r?
It is 2*r^2.
A 5 by 12 is inscribed in a rectangle what is the radius of the circle?
