Length of Terrestrial Telescope Solution

Follow our step by step solution on how to calculate Length of Terrestrial Telescope?

FIRST Step Consider the formula

L tt = f o + 4 \cdot f + \frac{D \cdot f e}{D + f e}

Next Step Substitute values of Variables

∴

L tt = 100cm + 4 \cdot 5.5cm + \frac{25cm \cdot 4cm}{25cm + 4cm}

Next Step Convert Units

∴

L tt = 1m + 4 \cdot 0.055m + \frac{0.25m \cdot 0.04m}{0.25m + 0.04m}

Next Step Prepare to Evaluate

∴

L tt = 1 + 4 \cdot 0.055 + \frac{0.25 \cdot 0.04}{0.25 + 0.04}

Next Step Evaluate

∴

L tt = 1.25448275862069m

Next Step Convert to Output's Unit

∴

L tt = 125.448275862069cm

LAST Step Rounding Answer

∴

L tt = 125.4483cm
