Distance between Front and Rear Wheel Solution

Follow our step by step solution on how to calculate Distance between Front and Rear Wheel?

FIRST Step Consider the formula

l fr = 2 \cdot R 2 \cdot W m - {W m}^{2}

Next Step Substitute values of Variables

∴

l fr = 2 \cdot 32m \cdot 0.37m - {0.37m}^{2}

Next Step Prepare to Evaluate

∴

l fr = 2 \cdot 32 \cdot 0.37 - {0.37}^{2}

LAST Step Evaluate

∴

l fr = 23.5431m
