Question

The slant height of the frustum of a cone is 5cm. if the difference between the radii of its two circular ends is 4cm,
write height of the frustum.​

Answer 1

Answer:

Hello!! Here is your answer

Height of the frustum of cone is 3 cm.

Step-by-step explanation:

$h = \sqrt{ {l}^{2} } - \sqrt(r1 - r2) ^{2} \\ h = \sqrt{ {5}^{2} } - \sqrt{ {4}^{2} } \\ h = \sqrt{25 - 16 } \\ h = \sqrt{9} \\ h = 3$

Answer 2

Answer:

L =root h^+(r1^ -r2^)

so.

h= root 5^ -root 4^

= root (25-26)

root 9

so ..

h=3.......ans...
