WebThe sector's angle is computed using the formula θ = L R; where L is the sector's arc length and R is the sector's radius. Now say L = R θ. When you make a cone using the sector, its arc length will become the cone's base perimeter. So you can write 2 π r = R θ; where r is the cone's base radius. Now you can find r to be R θ 2 π. WebSep 14, 2011 · The surface area of a cone of height 'h' is (Pi) r2 + (Pi) r l, where r - radius of the circle part (base) of the cone, l - slant height of the cone found by the Pythagoras formula as l2 = h2 + r2 and Pi = 3.14 approximately.
