Surface area = 4*pi*162 = 3216.99 square units to 2 decimal places
Surface area of a sphere = 4*pi*radius squared
SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
Surface Area of Sphere = 4*pi*r2 = 4*pi*22 = 16*pi
No, if you double the radius of a sphere, its surface area does not double; it actually increases by a factor of four. The surface area ( A ) of a sphere is given by the formula ( A = 4\pi r^2 ). When the radius ( r ) is doubled, the new surface area becomes ( A' = 4\pi (2r)^2 = 4\pi (4r^2) = 16\pi r^2 ), which is four times the original surface area.
If the diameter of a sphere is doubled, its surface area increases by a factor of four. This is because the surface area of a sphere is calculated using the formula (4\pi r^2), where (r) is the radius. When the diameter is doubled, the radius also doubles, leading to a new surface area of (4\pi (2r)^2 = 16\pi r^2), which is four times the original surface area.

SA of a sphere = 4pi(radius)^2 SA = 4(3.14)2^2 SA = 50.24
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 4, the surface area is4 (3.1416) (4)2 = 4 (3.1416)(16) = about 201.06 square units
Surface Area of Sphere = 4*pi*r2 = 4*pi*22 = 16*pi
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi

If the diameter of a sphere is doubled, its surface area increases by a factor of four. This is because the surface area of a sphere is calculated using the formula (4\pi r^2), where (r) is the radius. When the diameter is doubled, the radius also doubles, leading to a new surface area of (4\pi (2r)^2 = 16\pi r^2), which is four times the original surface area.
