What is surface area of spherical shell?

Surface area of a sphere = 4*pi*radius2 For a spherical shell, surface area = surface area of outer sphere - surface area of inner sphere = 4*pi*(outer radius)2 - 4*pi*(inner radius)2 = 4*pi*[ (outer radius)2 - (inner radius)2 ]

How do you calculate the surface area of a spherical tank with a diameter of 96 inches?

You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2


What is the surface area of a sphere with a radius of 7cm?

The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Plugging in the radius of 7cm, we get 4π(7)^2 = 4π(49) = 196π. Therefore, the surface area of a sphere with a radius of 7cm is 196π square centimeters.
