Radius of a Circle Formula: r = d/2
Area of a Circle Formula: A = πr²
Step-by-step explanation:
<u>Step 1: Define</u>
Diameter <em>d</em> = 18 units
<u>Step 2: Manipulate Variables</u>
Radius <em>r</em> = 18 units/2 = 9 units
<u>Step 3: Find Area</u>
- Substitute in <em>r</em> [Area of a Circle Formula]: A = π(9 units)²
- [Area] Evaluate exponents: A = π(81 units²)
- [Area] Multiply: A = 81π units²
Answer: Multiplying the number by 2.5
Step-by-step explanation:
Jay took a number, n, and increased it by 25%. The value gotten will be:
= n + (25% × n)
= n + (0.25 × n)
= n + 0.25n
= 1.25n
After that, Then, he doubled the resulting product. The value now gotten will be:
= 2 × 1.25n
= 2.50n
Therefore, the equivalent will be multiplying the number by 2.5. This will be:
= n × 2.5
= 2.5n
Therefore, it's thesame with the value gotten.
The correct option is D.
