Question

If the diameter of sphere is reduced by half, its surface becomes

Answer 1

The answer is: Its surface area becomes (1/4)th

Answer 2

If the diameter of sphere is reduced by half, its surface becomes one fourth of the original value.

Step-by-step explanation:

• The 'surface area' of a sphere is 'directly proportional' to the square of the 'radius'.

• Radius is half the diameter, so if diameter is halved, radius is also halved.

• This means that the surface area gets reduced by one fourth of the original value.

• In others words, when the diameter is halved, the surface decreases by a 'factor of four'.
