the formula for surface area of a sphere is 4pi(r squared)
so do
4x3.14x144
equals
576 pieunits^2
Assuming the 5.2 units are the radius of the sphere, then its surface area is: surface_area_sphere = 4πr² = 4 × π × (5.2 units)² = 108.16π units² ≈ 339.8 units²
true
You can find the surface area of a sphere by solving this equation: SA=4(pi)(r)(r) where SA is your surface area, and r is the radius. Your answer comes out to be about 1017.4 square units.
The answer is 36π or approximately 113.1 cm.
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 ]
The surface area of a sphere with radius 6 is: 452 square units.
The surface area of a sphere with a radius of 12 units is about 1,809.6 units2
The surface area of a sphere with a radius of 15 units is 2,827 units2
The surface area of a sphere that has a radius of 10 is: 1,260 square units.
The sphere's surface area is ~1,017.9 square units.
The surface area of this sphere is 2,123.7 units2676 units2
Surface area of the sphere = 4*pi*122 = 1809.557368 square units
The radius of the sphere is ~16.395 units.
Assuming the 5.2 units are the radius of the sphere, then its surface area is: surface_area_sphere = 4πr² = 4 × π × (5.2 units)² = 108.16π units² ≈ 339.8 units²
