[2/2 Formula]
Work: Calculate the value of equation 0003611*0.35/3.14*(sin(3.14*0.3)+sin(3.14*0.65)) .
Question type: Mathematical calculation
Solution:
0003611*0.35/3.14*(sin(3.14*0.3)+sin(3.14*0.65))
=0003611*0.35/3.14*(sin0.942+sin(3.14*0.65))
=0003611*0.35/3.14*(sin0.942+sin2.041)
=0003611*0.35/3.14*1.700212
=1263.85/3.14*1.700212
=402.5*1.700212
=684.33533
Answer:0003611*0.35/3.14*(sin(3.14*0.3)+sin(3.14*0.65))=684.33533
