You have a cone with a radius of 6 ft and a height of 12 ft. Find the area of the triangle formed by a perpendicular cross-section through the cone’s center.

Question

help please

Answer 1

This is geometry, so always make a sketch of the relevant situation, if possible.

I see h=12, base b =r=6 are the legs of a right triangle; area =36 sq ft. by applying the usual formula Area = ½bh.
