Hey mate here is your answer.
Given,
Given, radius, r = 10 cm
Given, radius, r = 10 cm slant height, l = 30 cm
Given, radius, r = 10 cm slant height, l = 30 cmNow,
Given, radius, r = 10 cm slant height, l = 30 cmNow, surface area of cone= πr (r+l)
Given, radius, r = 10 cm slant height, l = 30 cmNow, surface area of cone= πr (r+l) = 3.14 x 10 ( 10 + 30 )
Given, radius, r = 10 cm slant height, l = 30 cmNow, surface area of cone= πr (r+l) = 3.14 x 10 ( 10 + 30 ) = 31.4 x 40
Given, radius, r = 10 cm slant height, l = 30 cmNow, surface area of cone= πr (r+l) = 3.14 x 10 ( 10 + 30 ) = 31.4 x 40 = 1256
Given, radius, r = 10 cm slant height, l = 30 cmNow, surface area of cone= πr (r+l) = 3.14 x 10 ( 10 + 30 ) = 31.4 x 40 = 1256 So the surface area of the cone is 1256 cm sq.
