What is the use of a surface area calculator?

An  surface area calculator is an online calculator used to calculate the area of geometric solids, including a capsule, cubes, frustum, cylinders, pyramids, spheres, spherical caps, hemispheres, and triangular prism. The units are placed to indicate the order of the results, such as ft, ft2, or ft3. 

What are the various formulas of surface area?

The surface area of a sphere is A = 4πr2

r – Radius of the sphere

The surface area of a cube A = 6x2 

x – Side length of the cube

Surface area of a cone A = πr2 + πr√ (r2 + h2)

h – height 

r – radius of the cone

surface area of a cylinder A = 2 πr2 + 2 πrh

r – radius

h – the height of the cylinder

How to use the surface area calculator?

• Go to Cuemath's online surface calculator
• Select a three-dimensional figure from the list and enter the values in the input boxes.
• Click on the calculate button to find the surface area
• Click the reset button to clear the fields and enter the new values for the next calculation.

What is the surface area of the capsule?

The surface area of the capsule formula is defined as the measure of the total amount of 2d space enclosed by all the faces of the capsule. It is represented as SATotal = (2*π*rsphere) + cylinder)

The sphere radius of the capsule is a radial line from the focus to any point of a curve of the capsule, and the cylinder height of the capsule is the distance between the lowest and highest points of the cylinder.

How to get the surface area of a sphere?

Some simple steps are to get the result without facing any issues. The steps are as follows:

• You must have a radius or diameter to get the surface area
• The formula to find the surface area of a sphere A = 4πr2
• Formula is A = 4π(d/2)2
• Substitute the given values in the formula
• Perform the calculations and find the surface area
• In the formula, the value of π is 22/7 or 3.14
