The area of the circle is 50.265482457436691815402294132472 inches2. The area of the rectangle is 210 inches2. The rectangle is larger in area by 159.73451754256330818459770586753 inches2,
It is not. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
area of a circle = pi*r2
Find the area of both circles (A = πr2) and subtract the area of the larger circle from that of the smaller circle inside it.
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)

The area of the circle is 50.265482457436691815402294132472 inches2. The area of the rectangle is 210 inches2. The rectangle is larger in area by 159.73451754256330818459770586753 inches2,
pi X radius squared X the percent of the circle.
The formula for the area of a circle is, A = πr2 If the area is tripled then the larger circle has an area of A2 = πR2 (where R is the new radius) But, πR2 = 3πr2 : R2 = 3r2 : R = r√3 The circumference of the original circle was 2πr. The circumference of the larger circle is 2πR = 2πr√3 Therefore, if the area is tripled, then the circumference increases by √3.
We can look at total areas (and ignore units-they're all the same). The smaller circle has an area of 9pi, and the larger circle has an area of 25pi. The smaller circle is entirely inside of the larger circle. So anything not in the smaller circle is in the larger circle. 16pi square centimeters are part of only the larger circle. 16pi/25pi=.64. So the desired probability is .64.
Bolivia is larger, it's area is 424,163 square miles compared to Paraguay's area of 157,048 square miles.
The area is increased by 300%.

When the diameter is doubled, perhaps? Then the area is 4 x larger.
An annulus. Area = pi (R2 - r2) when R is radius of larger circle and r is radius of smaller circle.
