since the volume of a right cylinder is height x area of base, the area of the baseis Pi * r^2 (r is radius which is 1/2 of diameter), so the area of the base did notchange, while the height is doubled so the volume is doubled.
The base areas quadruple and the curved surface doubles.
The volume is doubled.
The surface area of the 'wall' doubles, but the base areas remain the same.
It doubles The volume of a cylinder height times diameter squared times 3.14
The volume will be doubled.
its volume is also doubled...
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
The cylinder's diameter will be about 32.58m
