If you know the diameter of a sphere you can calculate the surface area based on the following formula. A Sphere surface area. Surface Area of a sphere 4πr2 r diameter2 100 μm r 01 mm r 00001 m Surface Area of one Alveoli 4π00001m2 SA 1257x10-7 m2 Total Surface Area Number of alveoli SA 600000000 1257x10-7 m2 Total Surface Area.

When we write the formula for the surface area of a sphere we write the surface area of a sphere 4πr 2 4πr 2 4 area of a circle. Total surface area of a sphere is measured in square units like cm 2 m 2 etc. Integrating da over all θ gives the formula for the total surface area of a sphere.

Answer 1 of 4. A sphere is a three-dimensional shape that is round like a circle. If r is the radius of sphere then the total surface area of sphere is given by Total surface area of sphere 4πr2.

A 4πR 2. D Diameter Calculating the Surface Area of a. The radius is the distance between the centre and any point on the surface of a sphere.

So total surface area of sphere will be given in terms of radius only and hence that would be given as. The formula to calculate the surface area of a sphere is given by. Simply so what is the formula for the lateral surface area of a sphere.

A spheres surface area is measured in square units. Enter the radius of a sphere. Here the value of π is 22 7 and r.

The total surface area of a sphere 4 π r 2 From the equation we can say that the surface area of a sphere is directly proportional to the. The distance between the boundary and the centre point of the sphere is called the radius r. The sphere is defined as the set of points that are equidistant from the centre point in a three-dimensional area.

Calculating the Surface Area of a Sphere Using Diameter. So we know the sphere has only one characteristic with measurements that is radius. The total surface area of sphere is four times the area of a circle of same radius.

This is the total area of the surface of a sphere with the specified radius. π Pi 314159 r Sphere radius. For the diameter did you mean 200 μm.

If you only consider the exterior surface its the same as a solid sphere of the same radius 4pi r2. The total area of a sphere refers to the region covered by the spheres outer surface. The formula used to calculate sphere volume is.

Archimedes first derived this formula 2000 years ago. A sphere differs from a circle in the aspect that a circle is a two-dimensional 2D form but a sphere is a three-dimensional 3D shape. 1 d 4.

3 PW App Link - htt. A ϖ d 2. Where A Surface Area ϖ Pi 314159265.

Total surface area of sphere 4 π r 2 1 The radius and height of the cylinder that just encloses the sphere of radius r and 2r respectively. The three-dimensional version of a circle is known as a sphere. If you also consider the interior surface as if you were planning to paint the interior and exterior of a sphere that could be separated into two hemispheres it would.

The ratio of the total surface area of a sphere and a hemisphere of same radius isa 2. 1 b 3. 2 c 4.

Where R is the radius of sphere. A 4 π r 2.
