Work: Calculate the value of equation π*(48.3/2)^2-π*(40.3/2)^2 .
Question type: Mathematical calculation
Solution:
π*(48.3/2)^2-π*(40.3/2)^2
=π*24.15^2-π*(40.3/2)^2
=π*24.15^2-π*20.15^2
=π*583.222499999999968-π*20.15^2
=π*583.222499999999968-π*406.022499999999923
=1832.247521-π*406.022499999999923
=1832.247521-1275.557303
=556.690218
Answer:π*(48.3/2)^2-π*(40.3/2)^2=556.690218
