If im not wrong

Answer

volume increases with a  factor of 27

Explanation;

The volume of a sphere is given by the formula

V = 4/3 πr³

When the radius is 2 cm the volume will be;

V = 4/3 π (2)³

 = 32/3 π

When the increases to 6 cm the volume will be ;

V = 4/3 π (6)³

= 864/3 π

Hence, the volume increases by a factor;

(864/3 π) ÷ (32/3 π)

= 27

Thus, the volume increases with a factor 27
