Surface area of a sphere is defined as the total area covered its outer surface. A sphere has surface area equal to 4 π r2 square units. Learn easy and best methods to calculate the surface area of spherical objects at BYJU’S
Reasons to Calculate the Surface Area and Volume of a Sphere Lesson Summary FAQs Activities What is the area of the sphere? The area of a sphere and the surface area of a sphere are the same. The surface area is the quantity that covers the entire sphere. The formula for the surface...
So, what’s the surface area of a sphere formula?Surface area of the sphere $= 4\pi r^{2}$, where “r” is the sphere’s radius.In terms of diameter, when “d” is the diameter of the sphere, the surface area of a sphere is expressed as S $= 4\pi (\frac{d}{2})^{2}...
1. 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 sp...

Surface Area of a Sphere Formula via Archimedes Approximation MethodPhaovibul, M Tip E
Finding surface area of solid figures such as the cube, the cylinder, and so forth is explained here thoroughly.Surface area of a cube Here, not only we show you how to get the formula for the surface area of a cube using the cube template, we also illustrate the concepts with good ...
We define the area of such a surface by first approximating the curve with line segments. Revolving a line segment about the x-axis produces the curved surface of a frustum (a cone cut off parallel to its base), the area of which is given by the formula π(R1 + R2)L, where R1 ...
The surface energy is the energy required to create one unit of surface area. Such a process is schematically illustrated in Fig.1, and its energy is the difference between the total energies of system 2, in which the additional surface area A has been created, and system 1, which is the...
Surface area to volume ratio is simply an object’s surface area divided by its volume. It gives the proportion of surface area per unit volume of the object (e.g., sphere, cylinder, etc.). Therefore, the formula to calculate the surface area to volume ratio is: SAVOL=surface area(x2...
