Answer:

210.25 or 210.3495409 depending on how your teacher does it

Step-by-step explanation:

Looking for circumference of the circle when it asks for perimeter

Formula for Circumference C = π x r <em>3 (cubed)</em>

The diameter is 10 so you take half of ten or 10 ÷ 2 = 5

5 x 5 x 5 = 125 (r squared equation)

125 x π = 392.6990817

Some classes ans stuff use 3.14 for pi so i'll show it that way too

125 x 3.14 = 392.5

(equation with π)

392.6990817 ÷ 2 = 196.3495409

196.3495409 + 14 = 210.3495409

(equation with 3.14)

392.5 ÷ 2 = 196.25

14 + 196.25 = 210.25

1.What must be used to tell if a collection of items is a set?
Mnenie [13.5K]
1. A set is described either by listing all its elements between braces { } (the listing method), or by enclosing a rule within braces that determines the elements of the set (the rule method).
Example: So if P(x) is a statement about x, then S = { x | P ( x )} means “S is the set of all x such that P(x) is true.”

2. Types of set:
• Empty, or null, set {∅}.
• finite sets
• infinite set.

3. An infinite set: The set whose elements cannot be listed, i.e., set containing never-ending elements. Example: Set of all points in a plane.

4. The union of two given sets is the smallest set which contains all the elements of both the sets. To find the union of two given sets A and B is a set which consists of all the elements of A and all the elements of B such that no element is repeated. The symbol for denoting union of sets is ‘∪’.

The union of sets A and B, denoted by A ∪ B, is the set of elements formed by combining all the elements of A and all the elements of B into one set.
