Jul 8, 2024 · The surface area of a sphere with a diameter of 8 cm is 201.06 cm 2. To obtain this result, follow these steps: Multiply the diameter by itself to get the diameter squared: d 2 = 8 2 = 64 cm 2. Multiply the diameter squared by pi to obtain the sphere's surface area: A = π × d 2 = π × 64 cm 2 ≈ 201.06 cm 2. Verify the result using our area ...
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
4 days ago · Surface Area of a Sphere. A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance r r (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices. A sphere with radius r r has a volume of \frac {4} {3} \pi r^3 34πr3 and a surface ...
Jan 16, 2024 · To find the surface area of a sphere, use the equation 4πr2, where r stands for the radius, which you will multiply by itself to square it. Then, multiply the squared radius by 4. For example, if the radius is 5, it would be 25 times 4, which equals 100.
Jun 11, 2023 · 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.
The surface area of a sphere is given by the formula Where r is the radius of the sphere. In the figure above, drag the orange dot to change the radius of the sphere and note how the formula is used to calculate the surface area.
Mar 18, 2024 · This surface area calculator calculates the surface area of a sphere, cube, cylinder, pyramid, cone, and rectangular and triangular prism.
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: where r is the radius of the hemisphere.
Surface Area of a Sphere. Unlike a cone, cube, or cylinder, a sphere does not have any edges. So a sphere has only one continuous surface. And the area covered by this surface is the surface area of the sphere. Formula | Surface Area of a Sphere. For a sphere with a radius \hspace {0.2em} r \hspace {0.2em} r, the surface area is given by.
The surface area of a sphere is the area covered by the outer surface of the sphere. Learn how to determine the surface area of a sphere using examples.
