Work: Calculate the value of equation 13×π×8^2+4×π×(12.5)^2 .
Question type: Mathematical calculation
Solution:
13×π×8^2+4×π×(12.5)^2
=13×π×8^2+4×π×12.5^2
=13×π×64+4×π×12.5^2
=13×π×64+4×π×156.25
=40.840704×64+4×π×156.25
=2613.805056+4×π×156.25
=2613.805056+12.566371×156.25
=2613.805056+1963.495469
=4577.300525
Answer:13×π×8^2+4×π×(12.5)^2=4577.300525
