Does the circumference of a circle vary directly with its radius?
yes
What is a proportional ratio?
In mathematics, two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
How would you find the radius of a circle with a circle with a circumference of 68cm?
First, divide the circumference by Pi (about 3.1416): 68 / 3.1416 = 21.65 cm. This is the diameter. Now, divide the diameter by two to get the radius: 21.65 / 2 = 10.825 cm.The radius is: 10.825 cmNote: The result will vary slightly depending on the value you use for Pi
What is the square ft of a cylinder 18 by 32?
The answer will vary, depending on which of the two is the height, and which is the diameter of the base. To get the surface area, add up the two circles and the mantle, that is, use the formula: area = 2 x pi x radius2 + 2 x pi x radius x height, or the equivalent (2 x pi x radius)(radius + height).
What is the radius of the area covered by Congo red by potassium permanganate(KMnO)?
The radius of the area covered by Congo red when reacting with potassium permanganate (KMnO₄) depends on various factors, including the concentration of the solutions, the volume used, and the experimental conditions. Typically, in laboratory settings, the diffusion of KMnO₄ in a medium can create a measurable radius, but specific values would require empirical data. Generally, the radius is not fixed and can vary widely based on the parameters of the experiment.
What is the oxidation number and coordination number of rhodium in the coordination compound?
The oxidation number of rhodium in a coordination compound can vary, but it is commonly found in the +2 or +3 oxidation state. The coordination number of rhodium in a coordination compound is typically 6, as it can coordinate with up to six ligands.
What is the coordination number of phosphorus?
The coordination number of phosphorus can vary depending on its oxidation state and the molecules or ions that it is bonded to. In most common cases, phosphorus can have a coordination number of 3 or 5 in various chemical compounds.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
Does the circumference of a circle vary directly with its radius?
yes
What is the male to female ratio for black people?
The male to female ratio for black people can be find out :By finding the number of males who are black.By finding number of females that are black.By diving the number of male by female.
What is the student teacher ratio for kindergartner's in Florida?
The maximum student to teacher ratio in Florida is regulated by the senate. The maximum allowed number of students per teacher for grades preschool through 3rd grade is 18. The actual ratio will vary from school to school.
How does the nuclear radius vary with atomic mass number?
The nuclear radius generally increases with increasing atomic mass number due to the increased number of protons and neutrons in the nucleus. This leads to stronger nuclear forces that push the nucleons farther apart, resulting in a larger nuclear radius. However, there are exceptions and fluctuations in nuclear size due to specific nuclear properties and shell effects.
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.
What is the atom ratio of C to H?
The atom ratio of C to H in a molecule can vary depending on the specific compound. However, a common ratio in organic compounds is 1:1, meaning there is an equal number of carbon and hydrogen atoms in the molecule.
How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
What is the ionic radius of copper?
The ionic radius of copper can vary depending on its oxidation state. For example, the ionic radius of Cu2+ is approximately 73 pm, while the ionic radius of Cu+ is around 77 pm.
How much is the sand for a mix ratio cement in weight?
It depends on what you are mixing for. The ratio would vary for specific applications.
