A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.
Tamiku [17]
You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
V=540=\pi r^2*h= \pi r^2*15
Then,
r^2= \frac{540}{15 \pi }
So, r= \sqrt{\frac{540}{15 \pi }}
radius is approximately 3.4cm

Explain how to identify the restrictions on the variable when adding or
anastassius [24]

Rational expressions are those that have fractional terms. We state restrictions because it may cause the equation to be undefined in some values of x. The most common restriction for rational expressions is N/0. This means any number divided by zero is undefined.

<h3>What is rational expressions and examples?</h3>

A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions.

To find the restrictions on a rational function, find the values of the variable that make the denominator equal 0.
