total surface area of cone = πr² + πrl
total surface area of cone = π [(2r)²+2r×1/2]
total surface area of cone = π (4r²+r)
total surface area of cone =πr(4r+1) Ans

Heya mate
The answer of ur question is
Total surface area of cone = π r² + π r L
where r is base radius and L is slant height.
it's total surface is = π ( 2r )² + π r 1 / 2
= π r { 4r + 1 / 2 }
hope it helps
