Work: Calculate the value of equation 51×π×7^2+154×π×(12.5)^2+15×π×16^2 .
Question type: Mathematical calculation
Solution:
51×π×7^2+154×π×(12.5)^2+15×π×16^2
=51×π×7^2+154×π×12.5^2+15×π×16^2
=51×π×49+154×π×12.5^2+15×π×16^2
=51×π×49+154×π×156.25+15×π×16^2
=51×π×49+154×π×156.25+15×π×256
=160.221225×49+154×π×156.25+15×π×256
=7850.840025+154×π×156.25+15×π×256
=7850.840025+483.805269×156.25+15×π×256
=7850.840025+75594.573281+15×π×256
=7850.840025+75594.573281+47.12389×256
=7850.840025+75594.573281+12063.71584
=83445.413306+12063.71584
=95509.129146
Answer:51×π×7^2+154×π×(12.5)^2+15×π×16^2=95509.129146
