Formula for calculating the area of sphere is :
4 * pi * r * r
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
Surface area of a sphere = 4πr2
The formula for the surface area of a sphere is: 4 pi r 2
SA = 4 π r2 (SA is surface area = 4 (X) pi(3.142) (X) R(adius) squared
Surface area of a sphere = 4*pi*radius2
(4/3)*pi*r^3 pi is constant 3.14, r is radius of the sphere.
The formula for the surface area of a sphere is 4*pi*r2

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.
V=4/3*Pi*r3 where r is the radius.
Surface area of a sphere = 4*pi*radius2
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
