Area of Ring Solution

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

FIRST Step Consider the formula

A = \frac{π \cdot {D in}^{2}}{4}

Next Step Substitute values of Variables

∴

A = \frac{π \cdot {570mm}^{2}}{4}

Next Step Substitute values of Constants

∴

A = \frac{3.1416 \cdot {570mm}^{2}}{4}

Next Step Convert Units

∴

A = \frac{3.1416 \cdot {0.57m}^{2}}{4}

Next Step Prepare to Evaluate

∴

A = \frac{3.1416 \cdot {0.57}^{2}}{4}

Next Step Evaluate

∴

A = 0.255175863287831m²

LAST Step Rounding Answer

∴

A = 0.2552m²
