To work out the area of a sphere, you have to know its radius.
Once you know that:
-- 'square' the radius (multiply radius times radius)
-- multiply that result by 12.5664
The result is near the area of the sphere.

How do you work out the surface area of a sphere shape?
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).
Formula for area of a sphere?
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.
Sphere surface area?
Area of a sphere = 4(pi)r2
What is the formula for the suface area of a sphere?
Surface area of a sphere = 4πr2
How do you work out the area of a sphere shape?
to find the volume of a sphere the equation is v= 4 over 3 x pie x the radius cubed
Does a sphere have lateral 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.
How do you get the formula of the area of the sphere?
Surface area of a sphere = 4*pi*radius2
What is area of a sphere?
The area of a sphere with radius 'R' is [ 4 pi R2 ].
How do you determine the surface area of a partial sphere?
Take the surface area of the sphere as of it was whole, and divide by the amount of the sphere that is missing.
Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?
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.
What is the surface area of a sphere?
The formula for the surface area of a sphere is 4*pi*r2
Surface area of sphere?
Surface area of sphere is : A= 4*pie*r^2
