What will happen to a spheres volume if the radius is tripled?
The volume increases 27-fold.
Is the radius of a regular polygon always greater than the apothem?
yes the radius of a regular polygon is always greater than the apothem
A can of tennis balls consist of that 3 spheres of radius inside cylinder of radius r and height h?
I assume this is true or false... since it is only a statement and not a question. True
Is the diameter of the circle always greater than the radius of the circle?
No, only if the diameter is bigger than the radius is the radius smaller than the diameter.
If the ratio between the radii of two spheres is 23 then what is the ratio of their volumes?
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
What is a artificial dielectric?
The dielectric is composed of "molecules" that are actually perfectly conducting spheres. These have radius R and are in a cubic array with spacing much greater than the radius R. With the application of a voltage, the spheres acquire the positive and negative surface charges on their northern and southern poles required to make their surfaces equipotentials. In so far as the field outside the spheres is concerned, the system is modeled as an array of dipoles, each induced by the applied field.
Is there a radius on a rectangular prism?
No, only on shapes with circles such as cones and spheres.
What will happen to a spheres volume if the radius is tripled?
The volume increases 27-fold.
Two spheres one with radius 7 and one with radius 4 tangent to each other what is the maximun possible length?

What is the math definion of volume of spheres?
Four-thirds of pi times the cube of the radius
How do you solve this question Two spheres are cut from a certain uniform rock One has radius 4.50 cm The mass of the other is five times greater Calculate its radius?
Since volume = 1/density x mass and as the rock is uniform it has a constant density, the volume is directly related to the mass; meaning that since the mass of the second is 5 times as big as that of the first, the volume of the second is also 5 times as big as that of the first. The ratio of volumes is the cube of the ratio of lengths; so the lengths are in the ratio of the cube root of the ratio of the volumes. The ratio of the volumes in this case is 1:5 giving the ratio of the lengths as 1:3√5 So the second radius is 3√5 (≈ 1.71) times as big as the first, making it 4.50 cm x 3√5 ≈ 7.69 cm.
What is the radius of gyration of a flywheel in the form of a uniform cylinder of radius 0.43m?
For a solid cylinder, divide the radius of the flywheel by the square root of 2, to get the radius of gyration.
What happens if a circle's radius is tripled?
If the radius is tripled then the Area will be greater by a factor of 9. And the circumference will be greater by a factor of 3.
Is the radius of a regular polygon always greater than the apothem?
yes the radius of a regular polygon is always greater than the apothem
As the radius of a sphere gets larger which of the spheres measurements increases more the surface area or the volume?
The volume increases faster. (proportional to the cube of the radius)The surface area increases slower. (proportional to the square of the radius)
What is the formula for finding spheres volume?
Volume of a sphere = (4/3) x (pi) x (Radius)3
A can of tennis balls consist of that 3 spheres of radius inside cylinder of radius r and height h?
