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.

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 .

Two make a right circular conical tent 22 metre broad canvas is required. It is height of the tent is 28 metre and the area of the base is 1386 sq. metre then how long convas is required to make the tant?

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

The volume of a right circualr cylinder varies as the square of the radius of its base , when its height is constant and as the height when the radius of the base is constant . The volume of a cylinder the radius of whose base and height are respectively 2 metres and 7 metres is 88 cubic metres . The volume and radius of the base of a cylinder are 396 cubic metres and 9 metres respectively . Detemine the height of the cylinder.

Curved surface area of a cone is 308 cm ^(2) and its slant height is 14 cm Find. radius of the base .

A cylindrical tin can open at the top , of a given capacity has to be constructed . Show that the amount of the tin required will be least if the height of the can is equal to its radius

A cylindrical tin can, open at the top, of a given capacity has to be constructed, show that the amount of the tin required will be least if the height of the can is equal to its radius.

When will the magnitude of the resultant of two equal vectors be (i) sqrt(2) times and

A cylindrical tin can , closed at both ends of a given volume , has to be constructed . Prove that , the amount of tin required will be least , when the height of the can is equal to its diameter .

The height of a right circular cylindrical icecream box of radius 6 cm is 15 cm . This icecream is distributed among 10 children by 10 equal eight circular conical pot in such a way that after distribution the upper part of the pot becomes a semi - circle . If the height of the cones be 4 times of the radius of the base , then what will be the radius of the conical pots ?
