Mathematical calculators for percentages, averages, ratios, fractions, and scientific calculations.
Sector Area Calculator A circular sector is a portion of a circle bounded by two radii and the arc between them. The size of a sector depends on two values: the radius of the circle and the central angle that defines the slice of the circle. The Sector Area Calculator above determines the area of … Read more
Parallelogram Area Calculator A parallelogram is a four-sided polygon where both pairs of opposite sides are parallel. Because of this property, opposite sides are equal in length and the opposite angles are also equal. Parallelograms appear frequently in geometry, architecture, engineering, and physics problems. The Parallelogram Area Calculator above allows you to quickly determine the … Read more
Ellipse Area Calculator An ellipse is a two-dimensional geometric shape that looks similar to a stretched circle. Instead of having a single radius like a circle, an ellipse has two different radii known as the semi-major axis and the semi-minor axis. These two axes determine the overall size and shape of the ellipse. The Ellipse … Read more
Circle Area Calculator A circle is a perfectly round geometric shape where every point on the boundary is the same distance from the center. That distance is known as the radius. Calculating the area of a circle allows you to determine how much two-dimensional space the circle covers. The Circle Area Calculator above quickly determines … Read more
Trapezoid Area Calculator A trapezoid is a four-sided geometric figure that has one pair of parallel sides. These parallel sides are usually referred to as the bases of the trapezoid, while the perpendicular distance between them is called the height. Because the two bases have different lengths, calculating the area of a trapezoid is slightly … Read more
Triangle Area Calculator A triangle is one of the most fundamental shapes in geometry. It is a polygon formed by three edges and three vertices. Even though the triangle looks simple, calculating its area can be done in several different ways depending on the information available. The Triangle Area Calculator above determines the area of … Read more
What Is Area? Area is a measurement that describes how much space a flat, two-dimensional shape occupies on a surface. You can think of it as the amount of material required to completely cover a shape, such as paint covering a wall or grass covering a field. In geometry, area represents the two-dimensional counterpart of … Read more
What Is a Scientific Calculator? A scientific calculator is a type of calculator designed to perform complex mathematical calculations beyond basic arithmetic. It supports advanced functions such as trigonometric calculations, logarithms, exponents, square roots, and scientific notation. Scientific calculators are widely used by students, engineers, scientists, and professionals who need to perform precise mathematical computations. … Read more
What is a Ratio? A ratio is a mathematical relationship between two or more numbers that shows how many times one value contains another. Ratios are commonly written using a colon symbol ( : ), such as 2:1, or expressed as a fraction like 2/1. For example: 2 : 1 means the first value is … Read more
Average Calculator – Calculate Mean of Numbers What is an Average? The average (also called the mean) is a value that represents the typical number in a dataset. It is calculated by adding all numbers together and dividing the sum by the total count of numbers. Average Formula Average = Sum of all numbers / … Read more
