Answer 2

Answer:

The difference between the radii of its two circular ends is 6 cm

Step-by-step explanation:

Given : The slant height of the frustum of a cone is 10.if the height of frustum is 8 cm.

To find : The difference of the radii of its tow circular ends?

Solution :

Slant height = 10 cm

Height of frustum = 8 cm

Formula to find radii is

$l^2=h^2+(R - r)^2$

$10^2=8^2+(R- r)^2$

$100=64+(Rr)^2$

$(R-r)=\sqrt{36}$

$(R - r)=6$

Therefore, The difference between the radii of its two circular ends is 6 cm
