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
Tripling the radius of a sphere increases the surface area by a factor of?

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.
A spherical balloon is partially blown up and its surface area is measured More air is then added increasing the volume of the balloon If the surface area of the balloon expands by a factor of 3.7?
Area varies as (radius)2.Volume varies as (radius)3 = (area)3/2If area increased by the factor of 3.7, then volume increased by the factor of (3.7)3/2 = 7.117 times (rounded)
What happens to the surface temperature of a planet if you decrease its orbital radius?
If you decrease a planet's orbital radius, its surface temperature will increase.
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 resistance if radius of a wire is decreased by a factor of 3?
If the radius of a wire is decreased by a factor of 3, the resistance of the wire will increase by a factor of 9. This is because resistance is inversely proportional to the cross-sectional area of the wire, which is proportional to the square of the radius. So, decreasing the radius by a factor of 3 will result in the area decreasing by a factor of 9, leading to a 9-fold increase in resistance.
Doubling the radius of a sphere increases the surface area by a factor of?

If the radius of a sphere doubles does its surface area double?
The surface of a sphere is: A=4? r2 From this, the surface are changes as the square of the radius. It does not change linearly.
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.
