What is the formula of volume of the sphere?
The formula for the volume of a sphere is V = 4/3 πr³.
Why is 4/3 used in the volume of a sphere?
Since the cylinder/cone and hemisphere have the same height, by Cavalieri’s Principle the volumes of the two are equal. The cylinder volume is πR3, the cone is a third that, so the hemisphere volume is 23πR3. Thus the sphere of radius R has volume 43πR3.
What is radius of sphere?
The radius (r) is the distance from the exact center of the sphere to any point on the surface of the sphere. Generally speaking, you can find the radius of a sphere if you know the diameter, the circumference, the volume, or the surface area. It is the “space that the sphere takes up.”
What is the equation of 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 area and volume of a sphere?
D = 2 r. Surface Area of a Sphere. A = 4 π r2. Volume of a Sphere. V = (4 ⁄ 3) π r3.
What is the volume of a 6 cm sphere?
The volume of a sphere is equal to 43 times Pi π times the radius cubed. Substitute the value of the radius r=6 into the formula to find the volume of the sphere. Pi π is approximately equal to 3.14 .
What is the equation of cylinder?
A cylinder’s volume is π r² h, and its surface area is 2π r h + 2π r². Learn how to use these formulas to solve an example problem.
What is the volume of cylinder?
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm.
What is TSA and CSA of sphere?
Surface area (TSA) = CSA = 4πr2. Hemisphere : Curved surface area(CSA) = 2 π r2. Total surface area = TSA = 3 π r2.
How to calculate the volume of a sphere?
The volume of the spherical dome, which is a portion of a sphere cut off by a plane, can be calculated by the radius of the base of the dome and the height of the dome
How to calculate the size of a geodesic dome?
So if you have the coordinates for a geodesic dome with diameter 1 foot and you want to build a dome with diameter 20 feet, you can just take all the coordinates for your 1 foot dome and multiply them by 20 to obtain coordinates for the new one. Similarly, all the strut lengths will be 20 times as long, et cetera.

Which is the best approximation to a sphere?
Geodesic polyhedra are a good approximation to a sphere for many purposes, and appear in many different contexts. The most well-known may be the geodesic domes designed by Buckminster Fuller, which geodesic polyhedra are named after.
