If the height of the cone is 2 and the radius of the bottom is 2 root sign 3, the maximum cross-sectional area of the cone will be obtained

If the height of the cone is 2 and the radius of the bottom is 2 root sign 3, the maximum cross-sectional area of the cone will be obtained

Theorem: the cross-sectional area through radius is the largest, and it is an isosceles triangle
The cross-sectional area: &# 189; × (2 × 2 Number 3) × 2 = 4 number 3
