Inner circumference= 44dm

$2 \times \frac{22}{7} \times {r}^ = 44 \\ {r} = \frac{44 \times 7}{2 \times 22} \\ {r }= 7 \\$

area of inner c.s.a= 2πrh

area of inner c.s.a =2×22/7×7×3.5

area of inner c.s.a = 154dm

outer circumference = 45dm

2πr =45

2×22/7× r=45

r = 45×7/2×22

r = 7.15

area of outer c.s.a =2×22/7×7.15×3.5

area of uter c.s.a =157.3

1 dm =1m

total area =157+157.3= 314.3dm = 31.43m

cost of painting =31.43×2=62.86
