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 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.
What happens to surface area when dimensions are changed by a scale factor?
The area changes by the square of the same factor.
How does the surface area of a cube change if the length of each side is doubled?
The surface area is quadrupled.
How do you determine surface area of similar objects when it has a scale factor of 2?
For areas: Square the Scale Factor.
When a spherical cell increases in diameter from 2um to 20 um by what factor does its surface area change?
The surface area will increase one hundred fold.
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.
If the radius of a sphere doubles does its surface area double?
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
Consider a balloon that is being inflated As the balloon increases in size the area of its surface increases Each time the balloon's diameter doubles what do you expect for the change in the area?
The change in the area would increase by a factor of 4. When the diameter doubles, the radius also doubles. Since the formula for the surface area of a sphere is 4πr^2, when the radius doubles, the area increases by a factor of 4.
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.
What happens to surface area when dimensions are changed by a scale factor?
The area changes by the square of the same factor.
What happens to the greatest common factor of the cylinders' surface area if its radius is squared?
Nothing. The cylinder's surface area does not have a GCF.
Why is surface area not factor in experiment?
It depends on the experiment!
What happens to the Surface Area of a cube if each edge is multiplied by 7?
The surface area increase by a factor of 49.
Doubling the raduis of a sphere increase the surface area by a factor of?
By a factor of 22 = 4.
Surface area of a hypercube?
As you would find the surface area of a normal shape using scale factors: to find the volume scale factor cubed, therefore to find the surface area of the hypercube, you do the scale factor to the power of four. geoffrz450@yahoo.co.uk
Tripling the radius of a sphere increase the surface area by a factor?
By a factor of 32 = 9. In general, surface area (for any two similar objects) is proportional to the square of any linear measurement.
