Impoved Answer:-
Surface area of a sphere: 4*pi*radius squared
Volume of a sphere: 4/3*pi*radius cubed
The formula for the surface area of a sphere is 4πr2. The formula for the volume of a sphere is 4/3πr3.
Given the surface area, where S=surface area, the formula for finding the volume isV = √(S / 4pi)
You replace the radius in the formula, and do the calculations, to obtain either the volume or the area, depending on what formula you are talking about.
Volume of a sphere = 4/3*pi*radius3 Area of a circle = pi*radius2
The formula for the volume of a solid (not a sphere) is V=Bh, or the volume (V) equals the area of the base (B, or bh) multipied by the height of the solid (h).
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.

(pi)R2 is the formula for the area of a circle. It won't help you find the volumeof a half sphere, at least not without some calculus.What you need is the formula for the volume of a sphere: V = 4/3 pi R3 .Do I have to explain that the volume of a half sphere is just half of that ?

The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
What's more important is knowing the formulae for a sphere which are:- Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2
Volume = 4/3 * pi * radius * radius * radius Surface Area = 4 * pi * radius * radius
Technically, a circle is a 2-dimensional object, so the question should read "volume of a sphere" OR "Area of a circle". The formula to work out the volume of a sphere is: 4/3 pi x r3, where "r" is the radius of the sphere. To find the area of a circle: pi x r2.
Volume of a sphere = 4/3*pi*radius3 answered in cubic units Surface area of a sphere = 4*pi*radius2 answered in square units
