First work out the surface area of the solid
Area of cylindrical part:-
length of this part = 108 - 2*18 = 72 so its area
= 2 * pi * r * 72
= 2 *pi* 18 * 72 = 8143.01 cm^2
Area of the 2 hemispheres = 4 pi * 18^2 = 4071.50 cm^2
Total surface area of the solid = 12,214.51 cm^2
Cost of polishing = 12,214.51 * 7 = 85,501.58 paise

Answer:
So, the coefficient of x8 in the given expansion will be 210.
Step-by-step explanation:
We know,
General term in (x+a)n is given by,
Tr+1=C(n,r)xn−rar
∴ General term in (x2−1x)10 ,
Tr+1=C(10,r)(x2)10−r(−1x)r
⇒Tr+1=(−1)rC(10,r)x20−2rx−r
Now, we have to find the term having coefficient x8.
∴20−2r−r=8⇒r=4
So, T5 will have coefficient x8.
∴T5=(−1)4C(10,4)x8
⇒T5=10⋅9⋅8⋅74⋅3⋅2⋅1x8
⇒T5=210x8
Answer:
40 m/s/s.
Step-by-step explanation:
Acceleration = velocity / time
= 200 / 5
= 40 m/s/s.
