The sphere's surface area is ~1,017.9 square units.
Surface Area = 254.47 square units
Surface Area = 547.39 units square
If the surface area of the sphere is 4 m2, the radius is 0.5642 metres, approx.
Surface area of the sphere = 4*pi*122 = 1809.557368 square units
The surface area of a sphere with radius 6 is: 452 square units.
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
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.
r = 2.821 units
Surface Area = 547.39 units square
Surface Area = 254.47 square units
Surface Area = 547.39 units square
If the surface area of the sphere is 4 m2, the radius is 0.5642 metres, approx.
Surface area of the sphere = 4*pi*122 = 1809.557368 square units
Surface area of a sphere in square units = 4*pi*radius^2
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
