By a factor of 32 = 9. In general, surface area (for any two similar objects) is proportional to the square of any linear measurement.

If a radius of a sphere increase by a factor of 4 what does the factor of the volume increase?
64The formula to find the volume of a sphere is4/3 * pi * r3where r is the radius of the sphere. So if the radius is increased by a factor of 4, then the formula becomes4/3 * pi * (4r)3 = 4/3 * pi * 64r3showing that the volume increases by a factor of 64.
What is the radius of a sphere that has a surface area of 256?
The radius is 4.5135
What is the surface area of a cylinder with end that are half sphere with a radius of 4 and height of 12?
If the radius of the hemispheres is 4, then that leave 4 units for the length if the straight part of the cylinder. Total surface area = surface area of 1/2 sphere of radius 4 + lateral surface area of cylinder of radius 4 and height 4 + surface area of 1/2 sphere of radius 4. = surface area of sphere of radius 4 + lateral surface area of cylinder of radius 4 = 4*3*pi*43 + pi*42*4 = 469.1 cubic units.
What is the surface area of a sphere with a radius of 15 units?
The surface area of a sphere with a radius of 15 units is 2,827 units2
What is the surface area of an cylinder with the radius of 2 and height of 3?
The surface area of a cylinder with the radius of 2 and height of 3 is 62.83 units2

What happens to the area of a circle when you triple the radius?
As the area of a circle is pi*radius2 the increase in area is a factor of 32. So tripling the radius gives an increase in area by a factor of 9.
If the surface area of a sphere is increased by a factor of 4 what is the change in the length of the radius of the sphere?
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.
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
Quadrupling the radius of a sphere increases the surface area by a factor of?

What happens to the Surface Area and Volume of a pyramid if the radius and height are divided by 2?
The surface area is reduced by a factor 4, the volume by a factor 8.
If a radius of a sphere increase by a factor of 4 what does the factor of the volume increase?
64The formula to find the volume of a sphere is4/3 * pi * r3where r is the radius of the sphere. So if the radius is increased by a factor of 4, then the formula becomes4/3 * pi * (4r)3 = 4/3 * pi * 64r3showing that the volume increases by a factor of 64.
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
Which of the spheres measurements increases more the surface area or the volume?
If you increase the radius, the volume will increase more than the area.
Why the dot of water is always sphere?
Surface tension is in equilibrium. The shape of a sphere has the highest volume to surface area to radius ratio. This shape is the lowest energy level a volume of liquid can have. Deforming it into another shape would involve an increase in surface area and an increase in the average radius.
