What is the surface area of a sphere definition?
The surface area of a sphere is defined as the region covered by its outer surface in three-dimensional space. A Sphere is a three-dimensional solid having a round shape, just like a circle. The formula of total surface area of a sphere in terms of pi (π) is given by: Surface area = 4 π r2 square units.
How do u find the area of a sphere?
To find the surface area of a sphere, use the equation 4πr2, where r stands for the radius, which you will multiply by itself to square it. Then, multiply the squared radius by 4. For example, if the radius is 5, it would be 25 times 4, which equals 100.
What is the formula for finding the area of a sphere?
4*Pi*R2
Similarly, the volume of a ball enclosed by a sphere of radius R is (4/3)*Pi*R3. And the formula for the surface area of a sphere of radius R is 4*Pi*R2.
What is a sphere in physics?
A sphere (from Greek σφαῖρα—sphaira, “globe, ball”) is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space.
What is sphere in science?
Sphere. 1. (Science: geometry) A body or space contained under a single surface, which in every part is equally distant from a point within called its center. 2. Hence, any globe or globular body, especially a celestial one, as the sun, a planet, or the earth.
What is sphere and formulas?
D = 2 r. Surface Area of a Sphere. A = 4 π r2. Volume of a Sphere. V = (4 ⁄ 3) π r3.
What is the equation of a sphere?
Answer: The equation of a sphere in standard form is x2 + y2 + z2 = r2. Let us see how is it derived. Explanation: Let A (a, b, c) be a fixed point in the space, r be a positive real number and P (x, y, z ) be a moving point such that AP = r is a constant.
What is the formula for the surface of a sphere?
πr3 and a surface area of. 4 π r 2. 4 pi r^2 4πr2. A sphere has several interesting properties, one of which is that, of all shapes with the same surface area, the sphere has the largest volume.
What is the total surface area of a sphere?
The surface area of a sphere is the total area of the faces surrounding it. The surface area of sphere is given in square units. It was found by Archimedes, that if the radius of cylinder and sphere is “r”, the surface area sphere is equal to the lateral surface area of cylinder.
