What happens to the volume of a cone if the radius is double and the height is unchanged?

Since the volume of a cone is proportional to the square of the radius (look at the formula), double the radius would mean four times the volume.

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?
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.
When the radius of a circle is doubled what happens to the circumference?
since C=2Pixr, if we double r, we need to double C also. 2C=2Pix 2r
A cone surmounted by a cylinder surmounted by a hemisphere find its volume hemisphere 6m in height cylinder 7m in height cone 5m in height not given the radius or diameter?
The radius IS given, since height of hemisphere = radius of hemisphere!
What is the radius of a half circle when you have width and height?
If the half circle is on its flat side, the radius is its height. If the straight part of the half-circle is vertical, the radius is its width.
What happens to the volume of a cylinder if the radius is doubled?
V = (pi)*R2*H if you double the radius then put 2R in place of R in the formula: V = (pi)*(2R)2*H V = 4pi*R2*H So the volume will increase 4 fold if you double the cylinder's radius.
What happens to the radius if the volume of a cylinder is doubled?
It depends on whether the height remains unchanged or increases in the same proportion as the radius.
How do you double the volume of a cylinder?
Double its height or increase its radius by a factor of sqrt(2) = 1.4142 (approx) or some combination of changes to he height and radius.
What happens to volume if the radius and height decreases?
The volume decreases!
Will the surface area of a cylinder increase more if you double the height or double the radius?
it will increase more if you double the radius because the dimensions multiply and the curved surface has less area to cover as its height decreases and width increases
What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
Why does the volume of a clynder qaudruple when radius and height double?
If you notice the formulas you will see that the height and the radius are multiplied by 2, both of them. When you multiplied these together it will be like multiplying 2x2.
How do you find the diameter of a cylinder if the radius is 3 and the height is 6 meters?
Your diameter is double the radius. So the diameter is 6
What effect does tripling the radius and doubling the height of a cone have on the cone's volume?
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
What happens to the area of a circle if you double the original radius?
the area doubles. for example: the radius is 2. so the area is 4pi. then double the original radius of 2 to 4 and the area is 8pi. 8pi is double 4pi.
What happens to the volume of a cylinder if the radius and height are tripled?
The original volume is multiplied by 27.
What happens to the circumference of a circle if you double the radius?
The circumference also doubles.
What happens if double the diameter?
Nothing happens. A person sitting next to you won't know that you did anything to your circle. But you'll have a bigger circle. The radius will be double the originasl radius. The circumference will be double the original circumference. The area will be four times the original area.
