Work: Calculate the value of equation (π*(48.5/2)^2-π*(40/2)^2)*138*7.93/1000 .
Question type: Mathematical calculation
Solution:
(π*(48.5/2)^2-π*(40/2)^2)*138*7.93/1000
=(π*24.25^2-π*(40/2)^2)*138*7.93/1000
=(π*24.25^2-π*20^2)*138*7.93/1000
=590.815769*138*7.93/1000
=81532.576122*7.93/1000
=646553.328647/1000
=646.553329
Answer:(π*(48.5/2)^2-π*(40/2)^2)*138*7.93/1000=646.553329
