This question is not from class 11 .It is from class 10 . The following solution is here : a=sum of p term a=p/2{2A+(p-1)D} 2a/p={2A+(p-1)D}.........…..…...........….(1) b=sum of q term b=q/2{2A (q-1)D} 2b/q={2A+(q-1)D}.…..........................(2) & c = ,sum of r term 2c/r={2A +(r-1)D } ...….....…............(3) Multiplying (1) ,(2) &(3) by ,(q - r),(r - p) ,(p -q) &add , we get 2a/p(q-r)+2b/q(r-p)+2c/r(p-q) 2A×0+D×0=0

Volume of sphere =4/3πr³ =4/3*π*(6)³ And, volume of sphere= Volume of wire Or, 4/3π(6)³ = πr²h Or,. 4/3*(6)³= r²*36 Or,. r²=4/3×216/36 Or,. r² = 8 Or,. r=2√2cm Or,. r=2.282cm
