Question

Find the slant of a cone with surface area 103.67 square feet and radius 3 feet.

Answer 1

surface area of cone is
\(\Large \pi r (r+l)\)

r is the radius, l is the slant height

use this formula

Answer 2

l=(r^2+h^2)^1/2

Answer 3

u can calculate h with the help of surface area...

Answer 4

and l is ur slant height....

Answer 5

\(103.67 \approx 33\pi \)
r=3
\(33\pi = 3\pi (3+l)\)
only l is unknown :)

Answer 6

Thanks so much! I wasn't sure what formula to use. My final answer was h = 8 feet.
