The lateral area is 122.68m2
LA= πrsLA=piRS
The total surface area is 606.32 square inches. The lateral surface area is 405.25 square inches.
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.

The radius IS given, since height of hemisphere = radius of hemisphere!
The lateral area of this cone is 1884.96cm2
For a right circular cone, the lateral area is 565.49 units2
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
The lateral area is approximately 427.26 units2
This cone has a lateral surface area of approximately 226.73cm2
The lateral surface area is 565.49cm2
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
To triple the lateral surface area of a cone, you must increase the radius while keeping the height constant. The lateral surface area ( A ) of a cone is given by the formula ( A = \pi r l ), where ( r ) is the radius and ( l ) is the slant height. Since the slant height is related to both the radius and the height, adjusting the radius proportionately will achieve the desired increase in surface area. Specifically, you need to increase the radius by a factor of ( \sqrt{3} ) while maintaining the same height.
