Question

QuestionA right cone has a slant height of 20 feet, and the diameter of the base is 24feet. What is the height, h, of the cone?2024A. 544B. 16 ftC. 12 ftD. 256 ft

Answer 1

height of the cone can be found by,

`h^2=l^2-r^2`

l,slant height = 20

diameter =24

so radius =12

`h^2=20^2-12^2`
`h^2=256`

h=16

so the height is 16ft

Thus the answer is B (16 ft)
