The area of a circular ring is 90 if the radius of the outer circle forming the ring is 9 what is the radius of the inner circle of the ring assuming the circles forming the ring have same center?
Outer radius = a; inner radius = b; then area of the ring = pi (a2 - b2) = 90, where pi = 22/7. In view of a = 9, we have b2 = 81 - [90 x 7 / 22], the positive square root of which gives b.
How many square yards are in this roll of carpet?
That roll of carpet has the square yardage of its width measured in yards multiplied by its length measured in yards. You may need to unroll it to find the length exactly, or if you are only looking for an approximate area and hence length, you can assume the roll is made up of concentric rings of carpet, measure the diameter of each ring from the inside to the outside (to the backing of the carpet) and use these find the circumference of each ring and sum them - this sum can be calculated by summing the diameters and multiplying that sum by π. The last ring will not usually not be a full ring, so it can either be measured directly or added in as a fraction of the whole ring multiplied by its diameter.
