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
In this area of a sphere calculator, we use four equations: Given surface to volume ratio: A = 36 × π / (A/V)². Our area of a sphere calculator allows you to calculate the area in many different units, including SI and imperial units.
The surface area of a sphere is the entire region covered by its outer round surface. It is also the curved surface area of a sphere. Like all other surface area it is expressed in square units such as m 2, cm 2, and mm 2. We will learn how to find the surface area of a solid sphere. The equations are given below. Formulas. The basic formula is ...
The formula for the surface area of a sphere with radius r is: \text{Surface area}=4\pi{r}^{2} Notice that the square of the radius (r^2) occurs within the surface area formula. The surface area of a shape uses two-dimensions, so the units for surface area are units squared.
The formula for the surface area of a sphere, 4πr 2 is derived from the fact that its surface area is equivalent to the lateral surface area of a cylinder with the same radius and height equal to the diameter of the sphere. The diameter is twice the radius, thus leading to the factor of four.
A sphere with radius \(r\) has a volume of \( \frac{4}{3} \pi r^3 \) and a surface area of \( 4 \pi r^2 \). A sphere has several interesting properties, one of which is that, of all shapes with the same surface area, the sphere has the largest volume.
The surface area of a sphere is the total area that is covered by its outer surface. The surface area of a sphere is always expressed in square units. The formula for the surface area of a sphere depends on the radius and the diameter of the sphere. It is mathematically expressed as 4πr 2; where 'r' is the radius of the sphere.
The formula to find the surface area of sphere is 4 times of pi (π) and radius-squared (r 2). Surface area of sphere = 4 π r 2
The surface area of a sphere is 4πr 2. Since a hemisphere is half of a sphere, its surface area, S, is half the surface area of a sphere plus the area of the circular base (shown in gray) created by intersection of the plane and sphere:
Surface area of the sphere = 4 π 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 π (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).
