A wooden stool is in the form of a frustum of a cone with slant edge 40cm,top diameter 30cm and bottom diameter 50cm.

a) calculate the perpendicular height of the stool

4 answers

since the radii differ by 10cm,
h^2 + 10^2 = 40^2
a wooden stool in the form of a frustrum a cone with a slant edge 40cm top diameter 30cm and bottom diameter 50cm calculate perpendicular height of stool
ans 30.8
Hae,where is the answer?
