6 answers
A cone has a slant height of 8cm and a surface area of 50cm2. Find:(a) That Base radius of the height. (B) The perpendicular height of the cone. (C) The vertical Angles of the cone, to the nearest degree
Great
the vertical angle of a cone is 70 degree and it's slant height is 11cm. calculate the height of the cone
What is the formula for the vertical angle of a cone and please support with derivation and give examples
Could anyone please write me the original formula for the surface area if a pyramid? I would love to hear from you guys*☺*
