Made a diagram showing a crosssection of the tent
by ratios
height/ 176 = 112/64
height = 176(112/64)
= ....

The cone base radius is 176 cm.
Based upon similar right triangles,
112/64 = H/176
One of the triangles has the side of the tent for the hypotenuse, the radius for one side and the tent height for the other side. For the second triangle, the girl standing up is the vertical side, and the 64 cm length is the base. All angles are the same.
H = 308 cm
