The intersection of any set with the empty set is the empty set. This is because there are no elements in the empty set, and so the two sets have no elements in common. ... This is because the set of all elements that are not in the empty set is just the set of all elements. The empty set is a subseRead more

Acute angle is the angle whose measure is greater than 0 and less than 90 degrees. Right angle, whose measure is 90 degree. Obtuse angle is the angle whose measure is greater than 90 and less than 180 degrees. straight angle is the angle whose measure is 180 degree. Reflex angle is the angle whose mRead more

Circumference is a special case of perimeter. Both describe the total length of the boundary of a two dimensional figure, but circumference specifically refers to the perimeter of a curved figure or arc. Therefore it only applies to circles, ovals, ellipses, arcs, etc.

In geometry, area is the 2-dimensional space or region occupied by a closed figure, while perimeter is the distance around a closed figure i.e. the length of the boundary. For example, the area can be used to calculate the size of the carpet to cover the whole floor of a room. Perimeter can be usedRead more

Logarithms are a convenient way to express large numbers. (The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division. (This benefit is slightly less importantRead more

## is there any difference between Perimeter and Circumference?

## Abbas Khan

Circumference is a special case of perimeter. Both describe the total length of the boundary of a two dimensional figure, but circumference specifically refers to the perimeter of a curved figure or arc. Therefore it only applies to circles, ovals, ellipses, arcs, etc.
