R^2sin(theta)d(theta)d(phi)(r-hat)
The normal vector to the surface is a radius at the point of interest.
Area is NOT a vector.
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
Area of a sphere = 4(pi)r2
Surface area of a sphere = 4πr2

Area of a sphere = 4(pi)r2
Surface area of a sphere = 4πr2
area is scalar.because we will not say that your area in this direction and my area in this direction . so,area has only magnitude Answer2: the product of two displacements produce a vector area, AxB this is a vector area. BxA is an opposite area.
It is incorrect to say that sphere has lateral area. First sphere do not have sides like other geometric figure. In fact a line or plane can intersect the surface of a sphere in just one point. Sphere has no lateral side. It is enough to say surface area of sphere than lateral surface area of the sphere.
Surface area of a sphere = 4*pi*radius2
The area of a sphere with radius 'R' is [ 4 pi R2 ].
Take the surface area of the sphere as of it was whole, and divide by the amount of the sphere that is missing.
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
The formula for the surface area of a sphere is 4*pi*r2
