Calculate the Cross-sectional Area of a Wire
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
