AnsWer :
As we know that Volume of cylinder is given as :
Let the original radius be 'r' and height be 'h'.
As in the question stated that radius of cylinder is doubled mathematically it can be expressed as :
Now,we have also said in the question that, height of the cylinder is halved mathematically it can be expressed as :
So, the Volume of cylinder becomes as :
