Splet4sqrt(4^2 + h^2) pi = 20 pi sqrt(16 + h^2) = 5 Square both sides 16 + h^2 = 25 h^2 = 9 h = 3 cm Now that we know h and r we can find the volume V = 1/3 pi r^2 h = 1/3 pi (4^2)(3) = 16 pi cm^3.( = 50.27 cm^3) I hope my answer has come to your help. God bless and ahead! there. The lateral area of a right circular cone is 20pi cm^2 and the total ... SpletWe know that the lateral surface of the larger cone is π r ′ l ′ = 32 π so π ( k r) ( k l) = 32 π from which we get k 2 π r l = 4 π r l = 32 π ⇒ π r l = 8 π. Therefore, the lateral surface …
