Question

please answer my question​

Answer 1

Answer:

Given

Givenslant height = 2l

Givenslant height = 2lradius = r/2

Givenslant height = 2lradius = r/2total surface area of the cone = 2π*radius(radius+slant height)

Givenslant height = 2lradius = r/2total surface area of the cone = 2π*radius(radius+slant height)=2π*r/2[r/2+2l]

Givenslant height = 2lradius = r/2total surface area of the cone = 2π*radius(radius+slant height)=2π*r/2[r/2+2l]=πr{r+4l}/2 sq units
