Work: Calculate the value of equation 1/2×6.28×(60×3+180×28)+3.14×0.7×0.8×(800+5.0×20×(28-3)) .
Question type: Mathematical calculation
Solution:
1/2×6.28×(60×3+180×28)+3.14×0.7×0.8×(800+5.0×20×(28-3))
=1/2×6.28×5220+3.14×0.7×0.8×(800+5.0×20×(28-3))
=1/2×6.28×5220+3.14×0.7×0.8×(800+5.0×20×25)
=1/2×6.28×5220+3.14×0.7×0.8×3300
=0.5×6.28×5220+3.14×0.7×0.8×3300
=3.14×5220+3.14×0.7×0.8×3300
=16390.8+3.14×0.7×0.8×3300
=16390.8+2.198×0.8×3300
=16390.8+1.7584×3300
=16390.8+5802.72
=22193.52
Answer:1/2×6.28×(60×3+180×28)+3.14×0.7×0.8×(800+5.0×20×(28-3))=22193.52
