In terms of diameter, when “d” is the diameter of the sphere, the surface area of a sphere is expressed as S $= 4\pi (\frac{d}{2})^{2}$There are three types of surface area in solids: lateral surface area (LSA), curved surface area (CSA), and total surface area (TSA). ...
Understanding the concept of the surface area of a sphere is typically suitable for students in the8th gradeor higher. The idea is generally introduced after students fully understand area andvolumein two-dimensional shapes and simplethree-dimensional shapes, like cylinders and prisms. Math Domain Th...
How to derive the formula of the surface area of the sphere To derive the formula of the surface area of a sphere, we imagine a sphere with many pyramids inside of it until the base of all the pyramids cover the entire surface area of the sphere. In the figure below, only one of su...
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
