GIVEN ;-

⇒ Height of the cone = 24 cm

⇒ Radius of the base which is changed to sphere= 6 cm


TO FIND ;-

⇒ Radius of the sphere = ?


SOL :-

In the question it has written that the child has reshaped the cone as sphere so the formula  used to find out this question is ;-



               ⇒  Volume of cone = Volume of sphere


              
⇒ 1/3 × π× r ×² h            =   4 / 3 × π × R³


              
⇒           r² ×h                 =          4  × R³

           
              
⇒     6 ×6×24                  =          4  × R³

              
⇒      6 × 6 × 6                =         R × R × R

SO WHERE R IS EQUAL TO 6 CM

Therefore radius of the sphere = 6cm
