Given, radius of cylindrical bucket = r1 = 18 cm
Height of cylindrical bucket = h1 = 32 cm
Radius of conical heap = r2
Height of the conical heap = h2 = 24 cm
According to questions,
Volume of cylinder = Volume of conical heap
⇒πr21h1=13πr22h2⇒r21h1=13r22h2⇒18×18×32=13×r22×24⇒r22=18×18×4⇒r2=36 cm
∴ Radius of the iconical heap = 36 cm
Now, slant height of conical heap,
l=√r22+h22=√(36)2+(24)2=√1296+576=√1872=12√13 cm
