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.

Show that the right-circular cone of least curved surface and given volume has an altitude equal to sqrt(2) times the radius of the base.

Show that right circular cone of least curved surface and given volume has an altitude equal to sqrt2 times the radius of the base.

Water runs into an inverted conical tent at the rate of 20 ft^3 / min and leaks out at the rate of 5 ft^3 /min .The height of the water is three times the radius of the water's surface. The radius of the water surface is increasing when the radius is 5 ft, is

Find the area of canvas required for a conical tent of height 24m and base radius 7m.

A tent is of the shape of a right circular cylinder upto a height of 3 metres and then becomes a right circular cone with a maximum height of 13.5 metres above the ground. Calculate the cost of painting the inner side of the tent at the rate of Rs 2 per square metre, if the radius of the base is 14 metres.

A tent is of the shape of a right circular cylinder upt a height of 3 metres and then becomes a right circular cone with a maximum height of 13.5 metres above the ground. Calculate the cost of paintingthe inner side of the tent at the rate of Rs. 2 per square metre, if the radius of the base is 14 metres.
