WebNov 25, 2024 · To find the surface area of a sphere, use the formula (4πr 2 ), where r = the radius of the circle. Steps Download Article 1 Know the parts of the equation, Surface Area = 4πr2. This nearly ancient formula is still the easiest way to determine the surface area of a … WebMar 2, 2024 · To calculate the surface area of a sphere, all you need to know is the sphere's radius - or its diameter. A = 4 × π × r² where r is the radius. As we know that the diameter of a sphere is equal to two radii d = 2r, we can transform the equation into another form: A = 4 × π × (d / 2)² = π × d² where d is the sphere diameter. coop funeral notices berwick upon tweed
