Use the formula r = √(A/(4π)). The surface area of a sphere is derived from the equation A = 4πr2. Solving for the r variable yields √(A/(4π)) = r, meaning that the radius of a sphere is equal to the square root of the surface area divided by 4π.

In a neutral atom, the atomic and ionic radius are the same, but many elements exist as anions or cations. If the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.

2 × π r × h square units. If, for example, h = r so that the dome (light blue) is half of the sphere then the surface area of the dome is 2 π r2 square units, twice the area ofthe base (dark blue). If h is very small then the area of the cap can be much smaller than the area of the base.

The lateral surface area of a hollow cylinder is 5632cm2. It is cut along its height and rectangular sheet of width 44cm is formed.

A sphere has no edges and therefore no corners. It has one curved face that goes all the way around. A square based pyramid, a triangular based pyramid and a cone have a point at the top.

A man has solids of shapes (sphere, cube, cylinder, cuboid & cone) Area of base of cuboid is 110 cm². Radius of sphere and cylinder are equal but volume of cylinder is 25% less than the volume of sphere. Height of cone is equal to the edge of cube and volume of cube of volume of cone.

Relation between Diameter and Radius: Diameter of a circle is twice of its radius.

Because a 2d subshell would require both n = 2 and l = 2, which is not an allowed value of l for n = 2, a 2d subshell does not exist. Each subshell has 2l + 1 orbitals.

As with a circle, you need π (pi) to calculate the volume of a sphere. The formula is 4/3 × π × radius3.

There are two ends so their combinded surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side.

Hi Nicholas, The surface area of a sphere of radius r is 4 π r2. Half of this is 2 π r2. If this is what is meant by the surface area of a hemisphere then 2 πr2 = 1062.
