What is a formula for the volume of a sphere?
V = 4/3 πr³
The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.
What is total surface area of sphere?
Total surface area of sphere is. given by 4πr2 where is the. radius of the sphere i.e. T.S.A of sphere = 4πr2.
Why is the formula for surface area of a sphere?
The Greek mathematician Archimedes discovered that the surface area of a sphere is the same as the lateral surface area of a cylinder having the same radius as the sphere and a height the length of the diameter of the sphere. The lateral surface area of the cylinder is 2πrh where h=2r .
Is surface area a volume?
The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object. In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc. Each shape has its surface area as well as volume.
What is area of the sphere?
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 you calculate volume of sphere?
To find the volume of a sphere, we can calculate the volume by using a simple volume formula where we multiply 4/3 by pi by the radius cubed. The volume of sphere formula is unique because it only requires the radius to calculate the volume of any sphere.
What is the formula for finding the area of a sphere?
The basic formula for finding the surface area of a sphere is (4)pi*r^2, where r is the radius of the sphere, so you only need the radius of the sphere.
What is the equation for the volume of a sphere?
The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.
How do you calculate a sphere?
The formula for volume is 4/3 times pi times the radius cubed, or 4/3πr^3. The formula for surface is 4 times pi times the radius squared, or 4πr^2. Calculate the radius of the sphere from the information given about the sphere.
