a relation is a set of ordered pairs where the first element is called the ranged while the second element is the domain​

Mathematics

Answer:

False.

Step-by-step explanation:

We have the statement:

"a relation is a set of ordered pairs where the first element is called the ranged while the second element is the domain​"

A relation between two sets maps the elements of the first set into elements of the second set, creating an ordered pair.

So we can have a relation that maps elements X, into elements Y, and the ordered pairs will be (X, Y)

Where the set of the elements X is called the domain, and the set of elements Y is called the range.

Then the statement is false.

  • Radius: r = d/2
  • Surface Area of a Sphere: SA = 4πr²

Step-by-step explanation:

<u>Step 1: Define</u>

d = 19 cm

<u>Step 2: Find </u><em><u>SA</u></em>

  1. Substitute [R]:                    r = 19 cm/2
  2. Divide:                                r = 9.5 cm
  3. Substitute [SAS]:               SA = 4π(9.5 cm)²
  4. Exponents:                        SA = 4π(90.25 cm²)
  5. Multiply:                             SA = 361π cm²
  6. Multiply:                             SA = 1134.11 cm²
  7. Round:                               SA ≈ 1134 cm²
