Answer 2

$\huge\mathfrak\green{Answer}$

Let r¹ = 5 cm

and r² = 15 cm

πr¹ + r²l + πr² ............... (1)

From diagram we have,

AB = CD = 5 cm

DE = 15 - 5 =10 cm

And BD = 24 cm

BE² = BD² + DE²

= √576 + 100

= √676 = 26 cm = l

Metal required =

= π ( 5 + 15 )26 + π (5)²

= π x 20 x 26 + π x 25

= 5π (4 x 26 + 5)

= 5π x 109

= 5 x 22 / 7 x 109

= 1712.85 cm²
