How do you find the surface area of a sphere in calculus?

The surface area formula is given by A = 4 (pi) (r^2), where A = surface area and r = radius of the sphere. Hence, using the information given in the question, where r = 2, the formula yields A = 4 (pi) (2^2) = 50.27 cm^2. The surface area of the sphere is 50.27 cm^2. 2.

How do you find the 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.

How do you remember the surface area formula?

Surface Areas And Volumes

  1. To find the surface area of a solid, add the areas of all the faces. You can remember the formula as sum of areas of the all the faces. For example: For Cube.
  2. Volume of a pyramid is one third of area of its base times height. For Example:

How does surface area work?

Surface area is the area of all outer facing surfaces on an object. 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.
