Uhhhh i cant answer this without details
Answer:
-9π
Step-by-step explanation:
∫c (4y dx + 2xy dy)
= ∫∫ [(∂/∂x)(2xy) - (∂/∂y)(4y)] dA, by Green's Theorem
= ∫∫ (2y - 4) dA
Now convert to polar coordinates:
∫(r = 0 to 3) ∫(θ = 0 to 2π) (2r sin θ - 4) * (r dθ dr) --- first integration
= ∫(r = 0 to 3) (-2r cos θ - 4θ) * r {for θ = 0 to 2π} dr
= ∫(r = 0 to 3) -2πr dr
= -πr² {for r = 0 to 3}
= -π(3²) - -π(0)²
= -9π
Answer:
? = 32
Step-by-step explanation:
Because 8 times 4=32 plus 2 = 34 and therefore t=4 8 times 4 again plus 2 = 34 so 32 plus 2 =34

Answer:
Step-by-step explanation:
Tia wire length = 408 cm as 1 m=100cm
so total 10 pieces = 408/10 = 40.8 cm for one piece
Marta wire length = 540 cm
so total 9 pieces = 540/9= 60 cm for one piece
so martas wire is 19.2 cm longer than tia one piece ( 60-40.2)
Answer:
It is 10 you were right
Step-by-step explanation:
because if each one is 1/2 then each 2 is 1 then all the shape is 10
