Work: Calculate the value of equation 3*3.14*√(30.38^2-1)/2*ln(30.98+√(30.98^2-1)) .
Question type: Mathematical calculation
Solution:
3*3.14*√(30.38^2-1)/2*ln(30.98+√(30.98^2-1))
=3*3.14*√921.9444/2*ln(30.98+√(30.98^2-1))
=3*3.14*√921.9444/2*ln(30.98+√958.7604)
=3*3.14*√921.9444/2*ln61.943856
=3*3.14*30.363537/2*ln61.943856
=3*3.14*30.363537/2*4.126228
=9.42*30.363537/2*4.126228
=286.024519/2*4.126228
=143.012259*4.126228
=590.101187
Answer:3*3.14*√(30.38^2-1)/2*ln(30.98+√(30.98^2-1))=590.101187
