Calculate the Cross-sectional Area of a Wire

Question:
Calculate the cross-sectional area in units of m² for a wire that has a circular diameter of 0.12 m.

Answer:

🟢 Step 1: Use the formula for the area of a circle

The cross-sectional area A of a wire with a circular shape is given by the formula:

A = πr²

🟢 Step 2: Find the radius

The radius r is half of the diameter. Given:

Diameter = 0.12 m

r = 0.12 m ÷ 2 = 0.06 m

🟢 Step 3: Substitute into the formula

A = π × (0.06 m)²

A = π × 0.0036 m²

🟢 Step 4: Perform the calculation

A ≈ 3.1416 × 0.0036 m² ≈ 0.01131 m²

Final Answer: The cross-sectional area is approximately 0.0113 m²
