Answer:
L = 29,550 mm
Step-by-step explanation:
i think i've done this before.. but anyway Lets make it simple and easy.
Let A = 600mm
Let B = 300mm
Let C = 16 as number turns
Let d = 20mm
L = sqrt ((3.14 * (600 - 20))² + 300³) * 16
L = 29,550 mm
9y-3y=0
6y=0
Hope that helps
Answer:
254 
Step-by-step explanation:
Surface Area = 2Lh+2Lw+2wh
L=4 cm
h=9 cm
w=7 cm
Surface Area = 2(4)(9)+2(4)(7)+2(7)(9)
Surface Area = (72+ 56 +126)
Surface Area = (72+ 56 +126)
Surface Area =254
