Given radius: A = 4 × π × r²; Given diameter: A = π × d²; Given volume: A = ³√(36 × π × V²); and. 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.
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
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 ...
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 .
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.
Unlike a cone, cube, or cylinder, a sphere has only one continuous surface (without an edges). The surface area of a sphere is the area of that surface. It's given by the formula ...
Surface area of sphere explained with pictures, examples and practice problems worked out.
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.
Area of sphere or total surface area of sphere is the region covered by a surface of a spherical object in a three-dimensional space. Since the sphere is a complete curved shape therefore the curved surface area is equal to the total area of sphere.
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.
