We are given that the pyramid has a square base that is inscribed in the circular base of a cone.
" To inscribe something means to draw (a figure) within another so that their boundaries touch but do not intersect "
Hence we have to draw a figure such that the vertices of the square base of pyramid touch the points on the circle which is a base of a circular cone and also the top of the pyramid touches the top of the cone.
The figure of this question is attached to the answer.
