What is the radius of a sphere with a volume of 1/6 pie

Yakvenalex [24]

Answer:

$\large\boxed{the\ radius\ R=\dfrac{1}{2}}$

Step-by-step explanation:

The formula of a volume of a sphere:

$V=\dfrac{4}{3}\pi R^3$

We have

$V=\dfrac{1}{6}\pi$

Substitute:

$\dfrac{4}{3}\pi R^3=\dfrac{1}{6}\pi$ divide both sides by π

$\dfrac{4}{3}R^3=\dfrac{1}{6}$ multiply both sides by 3

$3\!\!\!\!\diagup^1\cdot\dfrac{4}{3\!\!\!\!\diagup_1}R^3=3\!\!\!\!\diagup^1\cdot\dfrac{1}{6\!\!\!\!\diagup_2}$

$4R^3=\dfrac{1}{2}$ divide both sides by 4

$R^3=\dfrac{1}{2}:4\\\\R^3=\dfrac{1}{2}\cdot\dfrac{1}{4}\\\\R^3=\dfrac{1}{8}\to R=\sqrt[3]{\dfrac{1}{8}}\\\\R=\dfrac{\sqrt1}{\sqrt8}\\\\R=\dfrac{1}{2}$

Can some one explain simplify and show me how to do it or give me a example

nika2105 [10]

When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.

What is the degree of the following Monomial -2f^2g^3h^5

jasenka [17]

Answer:

Step-by-step explanation:

We have a monomial in 3 variables: f, g and h. Whenever a monomial has more than one variable, the degree is calculated as the sum of exponents of all the variables involved. The given monomial is:

$-2f^{2}g^{3}h^{5}$

The exponent of f is 2, exponent of g is 3 and exponent of h is 5.

The degree of this monomial would be the sum of all these three exponents.

So, the degree of given monomial is:

Degree = 2 + 3 + 5

Degree = 10
