Galat likh rhe ho yrr TSA of cone Pie r (l+r) hota hai pagal jaisa padhate ho

[@key4learning197]

Dear
TSA of cone = pie r (l + r)
TSA of cone = pie r (r + l)
Both are correct
In addition, order does not affect the result of addition and multiplication.
Read the commutative property of addition
a + b = b + a
That's why r + l = l + r
Hopefully you will understand.
Think before react....
