Area of Brake Pad Solution

Follow our step by step solution on how to calculate Area of Brake Pad?

FIRST Step Consider the formula

A = θ p \cdot \frac{{R o}^{2} - {R i}^{2}}{2}

Next Step Substitute values of Variables

∴

A = 1.98rad \cdot \frac{{125mm}^{2} - {100mm}^{2}}{2}

Next Step Convert Units

∴

A = 1.98rad \cdot \frac{{0.125m}^{2} - {0.1m}^{2}}{2}

Next Step Prepare to Evaluate

∴

A = 1.98 \cdot \frac{{0.125}^{2} - {0.1}^{2}}{2}

Next Step Evaluate

∴

A = 0.00556875m²

LAST Step Convert to Output's Unit

∴

A = 5568.75mm²
