the volume changes as radius squared and linear with height, so tripling radius and double of height gives 3 x 3 x 2 = 18 times more volume
Radius
Doubling the radius quadruples the volume.
Yes its height is the same as its radius
The radius of a cylinder is independent of its height.
300. (Doubling the radius multiplies the area by four times.)
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
Radius
Doubling the radius quadruples the volume.
The surface area of the curved part of a cylinder is pi*r2h, where r is the radius and h is the height. If the height is tripled, the area becomes pi*r2(3h), or 3(pi*r2h). So if the height is tripled, the area of the curved surface is also tripled.
9
Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
nine:0
Four...
Yes its height is the same as its radius
Doubling the radius doubles the circumference.
Yes because diameter= r*2
The radius of a cylinder is independent of its height.
