Question

Find the volume of a cone with radius 30 in and slant height 50 in.

Answer 1

@Kevin

Answer 2

volume of a cone = (1/3)pi r^2 h where r = radius of base and h = altitude

Answer 3

r = 30 in slant ht , l= 50in
first find height h

h ^2 = l^2 - r^2
h^2 = 2500 - 900
h^2 = 1600

h = 40in

volume V= pi r^2 h /3
=> V= pi x 900 x 40 /3
=> V = 1200 pi in ^3

Answer 4

You can find the altitude from the radius and the slant height using pythagogoras
