General Formulas and Concepts:

Pre-Algebra

• Order of Operations: BPEMDAS
• Equality Properties

Geometry

• Radius: r
• Diameter: d = 2r

Explanation:

Step 1: Define

Radius = 12 cm

Step 2: Find diameter

1. Substitute: d = 2(12 cm)
2. Multiply: d = 24 cm

∴ The statement is false and should be 24 cm as the diameter.
