How do you find diameter from surface area?

How do you find diameter from surface area?

Calculate the Diameter of a Circle, from Its Area

1. Divide the area (in square units) by Pi (approximately 3.14159). Example: 303,000/3.14159 = 96447.98.
2. Take the square root of the result (Example: 310.56). This is the radius.
3. Now double the radius to get the diameter (Example: 621.12 meters).

What is the surface area formula for a circle?

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

How do you find the diameter of a circle calculator?

If you know the circumference of the circle, divide it by π to get the diameter. but you should use your calculator to get the most accurate results. If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm.

How do you find the diameter of a circle without the radius?

Divide the circumference (perimeter) by pi. That gives you the diameter.

What is an example of diameter?

Diameter is defined as the length of a straight line through the center of a circle. An example of a diameter is the length of a line sliced down the center of a pie. A straight line segment that passes through the center of a circle or sphere from one side to the other.

How do you calculate surface area?

The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units. Volume is the amount of space that a three dimensional object takes up.

Is diameter and width the same?

Diameter is the length of a line touching two points on a circle that passes through the center. Diameter exists only for circular, or for circle-based objects like a sphere or cylinder, thus the width and length should always be the same. The diameter is the same as the length or width of any circle.

How do you calculate the diameter of a circle?

The formula used to calculate the circle diameter is: ø = 2 x √(A / π) Symbols. ø = Circle diameter; A = Circle area; π = Pi = 3.14159… Area of Circle. Enter the area contained within a circle. Diameter of Circle. This is the diameter of a circle that corresponds to the specified area.

How is the surface area of a spherical cap calculated?

Spherical Cap. The surface area of a spherical cap is based on the height of the segment in question. The calculator provided assumes a solid sphere and includes the base of the cap in the calculation of surface area, where the total surface area is the sum of the area of the base and that of the lateral surface of the spherical cap.

How is the surface area of a capsule determined?

The surface area of a capsule can be determined by combining the surface area equations for a sphere and the lateral surface area of a cylinder.

Which is the formula for the surface area of a sphere?

The surface area formula for a sphere is 4 x π x (diameter / 2)2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius2. Visual on the figure below:
