Prove that a conical tent of given capacity will require the least amount of canvas when the height is `sqrt(2)` times the radius of the base.

Prove that, a conical tent of given capacity will required the least amount of canvas, when the height is sqrt2 times the radius of the base.

Show that a conical tent of given capacity will require the least amount of canvas when the height is sqrt2 times the radius of its base.

Show that a conical tent of given capacity will require the least amount of canvas when the height is sqrt(2) times the radius of its base.

Prove that a conical tent of given capacity will require the least amount of canvas when the height is sqrt(2) xx the radius of the base.

Prove that a conical tent of given capacity will require the minimum when the ratio between the height of the cone and radius of its base is sqrt(2):1

A conical tent of given capacity has to be constructed. The ratio of the height to the radius of the base for the minimum area of canvas required for the tent is
