Jul 19, 2024 · To find the surface area (A) of a sphere from its volume (V), follow these steps: Multiply the volume by itself to obtain the volume squared: V 2. Multiply this by 36 and pi to get: 36 × π × V 2. Take the cube root of this expression to obtain the surface area of the sphere: A = ³√ (36 × π × V 2).

Spherical cap volume calculation. The spherical cap, also called the spherical dome, is a portion of a sphere cut off by a plane. The formula behind its volume is: volume = ((π × h²) / 3) × (3r - h) or: volume = (1/6) × π × h × (3a² + h²) where the radius of the sphere is r, the height of the cap (the blue one) is h, and a is the ...
The calculator can estimate the volume and surface area of a hemisphere using the following formulas: Volume of a hemisphere: V = ( ( 4/3 )πr3 ) / 2. Surface Area of a hemisphere: A = ( 4πr2 / 2 ) + πr2 = 3πr2. Where π is the constant (3.141592654) To calculate the surface area of a hemisphere, the calculator first computes the surface ...

In geometrical analysis: “An object in three-dimensional space having resemblance in shape with that of a ball is termed a sphere”
Is circle and sphere the same?
No, a circle is a two-dimensional geometrical shape while a sphere is considered a three-dimensional object. Along a plane, the points on the circle are equidistant from the center of it. On the other hand, the points on the sphere surface are at the equal distances from the center at any of the axes present.
What is meant by the arc of the circle?
The term arc refers to the part of the circle. It has only two types which are designated as the minor arc and the major arc.
What are the most basic forms of angles?
The main types of the angles include: Obtuse angle >90o90^\text{o}90o Acute angle <90o90^\text{o}90o Right angle 90o90^\text{o}90o

Example: find the volume of a sphere. Only a single measurement needs to be known in order to compute the volume of a sphere and that is its diameter. For example, if the diameter is known to be 20 feet, then calculate the volume by using the first formula above to get 4/3 x 3.14159 x (20/2) 3 = 4.1866 x 1000 = 4188.79 ft 3 (cubic feet).
