How would the area of a circumerancebe affected when the diameter of a circle is doubled or triple?

First of all, there's no such thing as the "area of a circumference". The distancearound the circle is called the "circumference", and the area of the circle is calledthe "area of the circle".-- When the diameter of the circle is doubled, the circumference is doubledand the area is multiplied by 4.-- When the diameter of the circle is tripled, the circumference is tripledand the area is multiplied by 9.-- When the diameter of the circle is multiplied by N, the circumference ismultiplied by N and the area is multiplied by N2 .

What happens to the area of a circle if the circumference is doubled?

If the circumference of a circle is doubled, the area will be four times bigger. It's like having a square with one metre sides. If we double the length of sides, that is - two metre long sides. the length around will be eight instead if four metres. The area will not be doubled from one square metre to two square meters. It will be four square metres instead. Lengths only grow in one direction so doubling is doubling, but areas grow in two directions - length and width at the same time. Therefore, areas grow and grow, doubling this way and doubling that way, so the doubling is doubled making it four times. Trebling would be trebled making a three times length increase into a nine times area increase.

Why does the volume quadruple when the radius of a cylinder is doubled?

The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
