There are no images so it is impossible to tell how the dimensions of the sphere and square are related.
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units
Surface area = 20*pi square units
A(5) = 4 25
14
432 square units.
The answer is given below.
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units
144pi units2
144pi units squared
Surface area = 20*pi square units
180 units^2
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
160
144pi units^2

'Length' is the physical quantity that measures the linear spatial extent within an object and between objects. 'Width' is length from side to side. 'Depth' is length from top to bottom below a surface. 'Height' is length from top to bottom above a surface. And 'distance' is length between objects. In geometry, 'radius' is the length between a point on the circumference of a circle or sphere to the center. 'Diameter' is the length between two points on the circumference of a circle or sphere through the center. The meter is the basic unit of measurement of length according to the International System Of Units (SI). Astronomical lengths include the astronomical unit (AU), the light-year (ly), and the parsec (pc). The most common measuring tool for length is the straight-edge or ruler.
