Answer 1

Hey buddy ❤️❤️

Answer:

❤️❤️

Let radius of sphere = r 

Volume                    = 4πr³/3

Increased radius     = 2r 

Increased volume   = 4π(2r)³)/3

                               = 32πr³/3

difference 

4πr³/3 - 32πr³/3

4πr³(1/3 - 8/3 )

4πr³(-7/3)

-28πr³/3 amount of volume decreased 

magnitude = 28πr³/3 increased 

let p % of 4πr³/3  is 28πr³/3 

4pπr³/300 = 28πr³/3 

p/100        = 7

p               = 700 

P = 700 % 

Increased % = 700%

Hope it helps you ✌️✌️❤️❤️
