Some real-world examples of a sphere include a football, a basketball, the model of a globe, etc. All the points on its surface are equidistant from its center. Click to know more!Ī sphere is a 3D shape with no vertices and edges. The total surface area and the volume of a hemisphere formula are exactly half of the sphere area and sphere volume formulas.Ĭheck these interesting articles related to the sphere shape.In geometry, half of a sphere is known as a " hemisphere".The surface area of a sphere is 4πr 2 square units. The area of a circle is πr 2 square units. It has volume since it occupies some space. It extends in three directions, which are the x-axis, y-axis, and z-axis. The important differences between a circle and a sphere are as follows: CircleĪ circle extends in two directions, which are the x-axis and y-axis. The sphere's volume formula is given below:įor more details, check this article on volume of sphere.Ī circle and a sphere are two different shapes. The volume of a sphere is the measure of space that can be occupied by it. Check out the surface area of the sphere article for more details. In terms of diameter, the surface area of a sphere is given as S = 4π(d/2) 2, where d is the diameter.

Hence, the formula to find the surface area of a sphere is: The area covered by the outer surface of the sphere is known as the surface area of a sphere. NameĢπr, where π is a constant, which takes the value of 22/7 or 3.14 (approx) Considering a sphere to have a radius of 'r', the following table lists the important formulas of a sphere. It is measured in square units.Ī sphere shape consists of a radius, diameter, circumference, surface area, and volume.

Surface Area: The area occupied by the surface of the sphere is its surface area.

This amount of space occupied by it is called its volume.

Volume: Like any other three-dimensional object, a sphere also occupies some amount of space.

In the figure given below, the boundary of the dotted circle or the cross-section of the sphere containing its center is known as its circumference.

Circumference: The length of the great circle of the sphere is called its circumference.

The length of the diameter is exactly double the length of the radius.

Diameter: The length of the line segment from one point on the surface of the sphere to the other point which is exactly opposite to it, passing through the center is called the diameter of the sphere.

If 'O' is the center of the sphere and A is any point on its surface, then the distance OA is its radius (look at the image below for your reference).

Radius: The length of the line segment drawn between the center of the sphere to any point on its surface.

The important elements of a sphere are as follows:

Some examples of a sphere include a basketball, a soap bubble, a tennis ball, etc. From a mathematical perspective, it is a combination of a set of points connected with one common point at equal distances in three dimensions. The formula to calculate the area of an isosceles trapezoid is Area = (sum of parallel sides ÷ 2) × height.In geometry, a sphere is a three-dimensional solid figure, which is round in shape. What is the Formula for Area of an Isosceles Trapezoid? In a trapezoid, each side is of different lengths and the diagonals are not congruent, whereas, in an isosceles trapezoid the non-parallel sides are equal, the base angles are equal, the diagonals are congruent and the opposite angles are supplementary. What is the Difference Between a Trapezoid and an Isosceles Trapezoid? Find the Other Base Angle.Īccording to the property of an isosceles trapezoid, the base angles are equal, therefore if one base angle is 30°, then the other base angle will be equal to 30°. If One Base Angle of Isosceles Trapezoid is 30°. The two opposite sides (bases) are parallel to each other and the other two sides are equal in lengths but non-parallel to each other. In an isosceles trapezoid, the number of sides is four. What are the Properties of an Isosceles Trapezoid? The bases of an isosceles trapezoid are parallel to each other along with the legs being equal in measure. An isosceles trapezoid is a type of quadrilateral where the line of symmetry bisects one pair of the opposite sides. FAQs on Isosceles Trapezoid What is an Isosceles Trapezoid?Īn isosceles trapezoid is a type of trapezoid that has nonparallel sides equal to each other.
