How do you find the diameter of a sphere with the surface area?
Diameter of a sphere: d = 2 * r , Surface area of a sphere: A = 4 * π * r² , Volume of a sphere: V = 4/3 * π * r³ , Surface to volume ratio of a sphere: A / V = 3 / r .
How do you find surface area with only diameter?
Answers. 1. The formula for the area A as a function of the diameter d of a circle is given by A = π (d/2)^2.
Which is the formula for the surface area of a sphere with diameter D?
= 4 π r2
There are four main formulas for a sphere which include sphere diameter formula, sphere surface area, and sphere volume….Formulas of a Sphere.
| Sphere Formulas | |
|---|---|
| Diameter of a Sphere | D = 2 r |
| Surface Area of a Sphere | A = 4 π r2 |
| Volume of a Sphere | V = (4 ⁄ 3) π r3 |
Is the diameter the surface area?
The diameter of a circle is the straight-line measurement from one edge of the circle to the other, crossing through the center. The surface area of a circle, or any two-dimensional closed curve, is the total area contained by that curve.
How do you find the diameter of a sphere?
The diameter of a sphere can be found with the following equations:
- With given radius: d = 2 * r ,
- With given diameter: d = √(A / π) ,
- With given volume: d = ³√(6 * V / π) .
What will be the diameter of a sphere whose surface area is 50 5.44 Metre square?
Therefore, the diameter of the sphere is 4.2m.
What is sphere Byjus?
A sphere is a three-dimensional object that is round in shape. The sphere is defined in three axes, i.e., x-axis, y-axis and z-axis. This is the main difference between circle and sphere.
What is the nature of surface of a sphere?
A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices.
