Question

A cone has a circular base of radius 6mm.given that curved surface area of the cone is 84mmsquare find its slant height

Answer 1

Answer:

r = 6mm, CSA = 84mm , l= ?

Step-by-step explanation:

CSA(cone) = pie × r × l

84 = 22/7 × 6 × l

84 × 7 / 22 × 6 = l

49/11 = l

so, 4.46 is the slant height of the cone.
