T ep = 3.1416 \cdot 1.5E+8 \cdot (\frac{{0.08}^{3}}{2} \cdot (1 - {(\frac{0.04}{0.08})}^{4}) + (\frac{2}{3} \cdot {0.1}^{3}) \cdot (1 - {(\frac{0.08}{0.1})}^{3}))

Next Step Evaluate

∴

T ep = 257526.821790267N*m

Next Step Convert to Output's Unit

∴

T ep = 257526821.790267N*mm

LAST Step Rounding Answer

∴

T ep = 2.6E+8N*mm
