Answer: Volume of the cylinder is 75π or 235.62 cm³
Volume of cylinder =πr²h
where r is radius and h is height.
Here given radius = 5 and height = 3
Using the formula: πr²h
: π * 5² * 3
: π * 5 * 5 * 3
: 75π or 235.62 cm³
216 I think because 3 times negative 2 is -6 the -6^3=6*6*6=216
Inequalities and equations are alike in that they both involve two sides of a sign (whether it is an equal sign or an inequality sign) being compared. For example, both y = x + 2 and y > x + 2 are just ways of comparing the values of x and y.
They are different in that equations give a set number of definite answers (such as x = 2 and y = 3), while inequalities give an infinite number of answers (such as every number from 3 to infinity). Equations give a definite value to a variable, while inequalities give infinite possibilities, cutting out the regions that are impossible.
The laws of exponents I will be using are:
